Universal remote control for TV, how to set it up? Installation of electrical panels and control panels Installation of control panels.
Panels and consoles manufactured in factories are delivered to the construction site as complete, fully assembled units. For ease of transportation, complete panels are delivered in separate blocks up to 4 m long with all the parts for connecting them. Within the transported unit, all interpanel connections are made at the manufacturer's factory. Busbars are dismantled and delivered in separate packaging; sometimes measuring instruments, relays and apparatus are also dismantled before shipment.
The surfaces of live parts and unpainted parts of mechanisms are lubricated with technical petroleum jelly before packaging. Shields or their blocks are transported in a vertical position with braced braces and stops. For stability and ease of transportation, panel-type panels are secured with braces, which are removed after the panels are installed.
Panels supplied separately, in separate panels or cabinets, are pre-assembled in the workshops of the installation organization into separate blocks and transported to the installation area complete with busbars, taps, leads to resistance boxes, etc. Manufacturers send the necessary documentation along with the panels: schematic diagrams for each block; connection diagrams and specifications of installed equipment and devices.
Multi-panel panels in the MEZ are assembled in enlarged blocks of several panels in a block based on the conditions of transportation and installation on site (crowded panel rooms, size of installation openings, use of lifting mechanisms), with fully completed busbars, wiring of secondary circuits and preliminary adjustment. At the junction points of the blocks, all bus joints and connections of secondary circuits are marked and disconnected during transportation. The installation of blocks and their assembly into panels is carried out on pre-installed embedded metal structures with the restoration of inter-block connections according to markings and the connection of wires and cables for external communication.
Control panel panels are assembled on structures equipped with the necessary brackets, tags and ends for outgoing feeders. Resistance boxes are installed on structures and communication wires are laid along mounting rails. When fully assembled, magnetic stations are equipped with three or four panels in blocks up to 5 m long and weighing up to 3 tons with equipment in the form of inventory braces for transportation.
Loading and unloading of panels is carried out, as a rule, by cranes using inventory sling devices. When lifting a shield (block), the angle of inclination of the lifting cable to the vertical axis should not exceed 60; if this requirement is not met, special lifting crossbeams are used. The unloaded panels are brought into place in the switchgear room through the mounting openings, and they are moved inside the room by winches and other mechanisms along guide rollers or on a trolley.
In the panel room, before the installation of the panels begins, the following construction work must be completed: doors with locks are installed, glazed windows, cable channels with their ceilings are completed, clean floors, plastering, whitewashing and painting the room, ventilation and heating are installed. Openings and cable channels must be cleared of formwork, wooden plugs and construction debris. Before installation begins, builders must complete the work required by the project to seal the embedded parts.
For installation of panels it is necessary project documentation: drawings of the panel room indicating the installation location of the panel, channels, openings; a questionnaire issued to the manufacturer, a single-line diagram of the primary circuits and a wiring diagram; cable log and connection diagram.
Installation of panels and consoles.
Boards and consoles are made for various purposes, designs and methods of maintenance, however general principles installation is the same for everyone. Before installation, the panel is unpacked, inspected and checked for its condition, completeness of delivery, compliance with shipping documents and project drawings.
Installation of switchboards, like other elements of electrical installations, is carried out in two stages. In the first stage, simultaneously with the main construction work, electricians install the embedded parts provided for by the project in the building structure or supervise their installation by builders, lay pipes to switchboards, cabinets or consoles, prepare electrical wiring routes and grounding networks. Before starting the installation of the switchboards, it is necessary to complete the wiring of the lighting network, the laying of grounding lines and the installation of support structures for laying and fastening wires and cables connected to the switchboards or cabinets.
After graduation finishing works and acceptance of the premises for installation, the second stage of work is carried out: installing the switchboard, laying cables along prepared routes, installing cable couplings and seals, connecting cables and wires.
When preparing the shield for installation, marking work is performed. The purpose of marking is to determine on site the correct location of the switchboard or console in accordance with the project drawings and compliance with the required passage standards and distances between live parts. When marking the installation site, it is also necessary to ensure the correct alignment of the panel frame or console with openings and cable ducts, and the symmetrical arrangement of its longitudinal and transverse axes in relation to parts of the switchgear room. The PUE lists the permissible distances in electrical rooms that must be observed when installing the switchboard.
The initial marks for installing panels and consoles are the marks of the finished floor, indicated by the builders in several places. The marks are transferred using a hydrostatic level or level. Marking the installation locations for complete panels and control panels is greatly simplified and is reduced to marking the installation of the foundation frame.
The basis for any panel or console is a foundation frame, usually made from channels No. 8 or 10, which is bolted to the concrete floor. The length and width of the frame depend on the total length of the panel or console and the depth of the panels, as indicated in the installation drawing.
Blocks of switchboards and consoles, supplied by the manufacturer as a set or assembled at the MEZ, are installed on the foundation frame, aligned in the horizontal and vertical planes along the cord and plumb line and temporarily secured to the frame. After installation, connection and alignment of all panels and frames, the shield or console is finally bolted and additionally welded at several points to ensure reliable grounding. Boards and consoles can also be attached by welding to embedded parts pre-provided in the building elements. Fixed electrical structures are welded, and removable ones are bolted.
After installing and securing the panel or console, the ready-made busbars and branches from them that came with it are mounted. The assembly of tires consists of selecting them according to markings, connecting them to each other and connecting them to devices. After cleaning the contact surfaces of the tires from lubricant, check the quality of their processing. Tires can be assembled and secured to insulators if the contact surfaces do not have dents, cavities, irregularities, burrs, cracks or other mechanical defects visible to the eye. Noticed defects are eliminated by repeated processing: the tires are cleaned under a layer of technical petroleum jelly, which is then removed and replaced with a new one.
The tires are connected by electric welding or bolts. For bolted connections, galvanized bolts, nuts and washers are used. Other anti-corrosion coatings for bolts, nuts and washers, such as bluing, are also acceptable. Tires must be painted: single-lane tires - on all sides, and for multi-lane tires - only the outer surfaces of their packages. The bolt nuts are placed on the side convenient for observation and tightening, in particular when connecting busbars mounted flat, the nuts are placed at the bottom and the bolt heads at the top. After tightening the bolts, check the contacts with a probe 0.05 mm thick and 10 mm wide on at least three sides of the connection. In this case, the probe should not enter the contact more than 4 mm.
Having finished assembling the busbars, check the distance between the fixedly fixed bare current-carrying parts, as well as between them and the insulated metal parts of switchboards and consoles (they must be at least 30 mm along the insulation surface and 15 mm in the air).
After assembling, aligning and securing the panel or console, the devices, which arrived in separate packaging, are installed on the foundation frame. Installation of devices consists of inspecting each device without disassembling it, installing or connecting wires or cables to it. After making sure that they are in good working order, the devices are placed on the panel in accordance with the connection diagram. Relay measuring and recording devices are installed along horizontal and vertical axes common to each type of device. In this case, the permissible deviations from the marking axes for devices installed on one panel are no more than 1 mm, on different panels no more than 3 m. After installing the devices, connect the ends of the wires to them according to the connection diagram and check the condition of the secondary circuits and their compliance with the requirements set out in SNiP. All keys, buttons and control handles are provided with inscriptions indicating the operation for which they are intended (for example, “on”, “off”); Inscriptions on signaling devices indicate the nature of the signal.
When checking and adjusting, adjust the contact surfaces of the jaws, knife switches and tubular fuses so that when switched on, the knives easily and tightly fit into the jaws over the entire contact surface without distortions, gaps or other defects. The tight fit of the jaws to the knives when the switch or tubular fuse is in the on position is checked with a probe 0.05 mm thick and 10 mm wide, which should only pass between the knife and the jaw with difficulty. The drive position locks must work accurately. The drive must not allow the switch to switch off spontaneously.
In devices with sliding contacts (rheostats, voltmeter switches and others), it is necessary to ensure proper pressure of the moving contacts on the stationary ones along the entire length of their stroke.
Devices are installed vertically in a plumb line, with the exception of special types of devices intended for installation in horizontal and inclined positions. When installing, the devices are aligned so that the starting and ending points on the scale of each of them lie on straight lines, parallel to the longitudinal edges of the panels of the switchboard or console. Oil buffers of devices are filled with oil to the marks specified by the factory.
Next, they check the compliance of the completed installation work with technical conditions and standards. A detailed external inspection, electrical and mechanical tests are carried out. The insulation resistance of all secondary circuits of in-line connection, together with instruments and apparatus, is measured with a 500-1000 V megohmmeter and must be at least 0.5 MOhm. The mechanical strength of the fastening of switches and switches is checked by turning them on and off 30 times. If after this test no mechanical damage(misalignment of racks, jamming of lubricated rubbing surfaces), the switch or switch is allowed for use.
The shield is painted by the manufacturer. The busbars of control panels, alarms and relay protection are painted at the installation site in accordance with their purpose. It is not allowed to paint live parts of devices: places of bolted connections and connections of busbars to the terminals of devices, as well as sections of busbars at least 10 mm from the connection points, places of connection to portable grounding busbars. If the painting is damaged, the panel is painted again after all construction, installation and adjustment work. Painted surfaces must be matte without smudges, bubbles or scratches. The coloring of the shield elements must correspond to their purpose.
Inscriptions about the purpose of the lines are applied with black paint using a stencil on the back side of the panels. On the front side of the panels, sheets with inscriptions are placed in frames under the drives. Panel numbers are applied from left to right in the center of the lower chord. The name of the shield or console is indicated on the top frame.
Installation of switchboards, input devices, cabinets consists of the following installation operations: marking, installation and alignment of the frame; installation of panel blocks consisting of individual panels or sections on the frame; connecting the blocks to each other and securing them to the frame; connecting wires and cables; grounding.
Switchboards, input devices, shields are installed on a plumb line or level strictly vertically. Their distance from pipelines must be at least 0.5 m. Floor and apartment panels, when installed in niches, are secured with spacer bolts or embedded parts, as well as with dowel screws or plastic dowels with screws.
The modern design of floor distribution panels allows them to be installed before finishing work begins. The shields are equipped with a special contact device for connecting to the mains without cutting them and are usually installed in niches, less often on the wall. In the niches, the shields are secured with four spacer bolts located on the chassis, after which the main wires are laid.
Panels and points, input cabinets and power boxes are completed and assembled in workshops into blocks on a common frame in different combinations. Panel blocks assembled in the workshops arrive at the installation site in a completely finished form: painted, with inscriptions, complete with auxiliary materials for installation.
Complete devices with voltage up to 1000 V in volumetric design.
Complete volumetric devices are rooms with fully assembled, adjusted and tested equipment. These include control posts for electric drives of mechanisms, rooms for control station consoles, parts of machine rooms, volumetric panels (Fig. 3) of control stations, etc.
Completely ready-made, assembled and equipped control rooms are delivered to the installation site, they are installed in prepared places and connected with external cables to other electrical equipment.
Volumetric electrical installations can consist (depending on the overall overall dimensions) of one or several ready-made transportable sections, articulated at the installation site into a single structure. Let us consider, as an example, the premises of control stations for rolling mills. The room is a frame structure welded from bent and rolled profiles, with control posts located inside. The floor and ceiling are double, and the ceiling is also an air duct. The walls have external and internal cladding. The facade of the posts and part of the side walls are glazed. The floor slabs on which the remote controls are installed are partially (200 mm wide strip) left unfastened (when removed, an opening is created for cable entry). The 3 m long control stations are non-demountable, while the rest consist of separate sections. Each section is a three-dimensional large-block device, supplied complete with control panels with all electrical connections within one section and electric lighting. The sections are connected to each other at the installation site with bolts along the entire longitudinal perimeter.
The posts can be installed both on the floor level and on special supports with a height of 1.8 to 4.5 m. In addition, the placement of control station panels in sealed cabinets in close proximity to the controlled mechanisms has become widespread, which does not require the construction of special rooms for switchboards, reduces cable communications and facilitates the operation of electrical equipment.
By purpose electrical panels and control panels can be:
· operational ones, from which the technological process is managed and monitored;
· non-operational, intended only for installation of apparatus, instruments and devices not directly used for control and monitoring technological process;
· combined, which can perform both operational and non-operative functions.
By constructive The design of the electrical panel can be:
· external or internal installation;
· floor-mounted and wall-mounted;
· metal and plastic;
· cabinets with one, two and multi-sections;
· with front, rear and double-sided doors.
For modern systems automation, taking into account the use of microcontrollers, all control equipment can be placed in wall-mounted one-sided small-sized cabinets, and non-operational equipment in plastic modular panels.
To install switchboards and control panels, you must have an installation diagram, a general outline drawing with a list of all elements, including installation accessories.
At layout of automation equipment on switchboards and consoles must be taken into account:
· purpose and number of instruments and devices;
· ease of installation and operation;
· aesthetic aspects appearance;
· service safety.
Rice. 1. DIN rail and installation of an electrical device on it: a - installation; 6 - dismantling
The configuration and dimensions of DIN rails are given in the IEC 60947-7-2 standard (IEC 60947-7-2:2002 Designation: Low voltage distribution and control equipment - Part 7-2 - Auxiliary equipment - Terminal blocks with protective conductor for copper conductors) .
Usually, connecting terminals are also installed in the cabinet on DIN rails, united by standard sizes depending on the cross-section of the connected wires. They are designed both for connecting external wires and for connecting devices located on different panels of the cabinet (for example, on the door).
The range of manufactured terminal connections is very extensive, both in design (screw, spring, for quick installation, single- and multi-tier, etc.) and in electrical parameters(clamping cross-section from 0.14 to 240 mm2, current up to 400 A and voltage up to 1000 V).
In Fig. Figure 2 shows the most common terminals mounted on any DIN rail configuration: screw (a), spring (b), for quick installation (c) and screw for grounding, painted yellow-green (d), which are used to connect protective neutral conductors PE.
If the project does not provide for separate control panels, then the following are located on the front panels or front doors of control cabinets:
· measuring and control instruments;
· lighting equipment;
· operational equipment (buttons, switches, etc.);
· mnemonic diagrams.
The listed devices are arranged into functional groups, usually in the order of the technological process.
Rice. 2. Types of terminal connections: a - screw; b - spring; in - for fast connection; g - screw for grounding
For floor-mounted control cabinets The recommended installation height for control equipment is (in mm from the floor to the bottom edge of the device):
· indicating instruments and signaling equipment: 950 - 1800;
· recording and recording instruments: 110 - 1700;
· operational control equipment: 800 - 1600;
· mnemonic diagrams: 1000-1900.
Preference is given to the lower limit. The same values must be adhered to when installing wall-mounted control cabinets directly on site.
Connections of devices and devices to each other are made in accordance with the connection diagram. According to SNiP 3.05.07-85, the connection of single-wire copper conductors of wires and cables with a cross-section of 0.5 and 0.75 mm2 and stranded copper conductors with a cross-section of 0.35, 0.5 and 0.75 mm2 to devices and apparatus, clamp assemblies should, as As a rule, they are performed by soldering if the design of their terminals allows this to be done. If copper conductors of the specified sections are attached to devices that have terminals for connecting to a screw or bolt, then the conductors of these wires and cables must be terminated with a ferrule.
In Fig. Figure 3 shows various types of cable lugs, selected depending on the design of the terminal of the connected device, and a tool for crimping the lugs.
Rice. 3. Designs of cable lugs and tools for crimping them: a - ring; b - fork: c - for quick connection; g - power; d - tubular; e - crimping tool
Single-wire copper conductors of wires and cables with a cross-section of 1.0; 1.5; 2.5; 4.0 mm2 can be connected directly under a screw or bolt, and stranded wires of the same or larger sections can be connected using lugs.
Each end of the wire or cable core at the point of connection to the device or device must be numbered with the number of the electrical circuit in accordance with the wiring diagram.
The most simple method marking is the application of a number with a marker (special felt-tip pen) on a piece of PVC tube, which is placed on the end of the wire before connecting it to the device.
A more progressive method is to use a holder that snaps onto the connected wire and into which a nameplate with the designation of the electrical circuit is inserted (Fig. 4, a). The same figure (Fig. 4, b) shows marking rings that allow standard or individual marking of terminals in a row.
Rice. 4. Modern methods markings electrical circuits during installation: a - using a snap-on holder; b - using marking rings
Previously, connecting wires were grouped into bundles using harsh threads and other tape insulating materials. This technology was very labor-intensive, unaesthetic and caused inconvenience during setup and repair (to replace the wire, it was necessary to cut the entire harness).
The listed disadvantages are completely eliminated when using perforated boxes (Fig. 5, a), installed along the perimeter of the mounting plane and between the rows of devices. In this case, the installation is carried out without laying out the wires, and after its completion, the boxes are closed with lids, which makes the appearance of the inside of the cabinet more aesthetic. To combine the wires of an interpanel flexible connection (for example, between the inner panel of a cabinet and the equipment on the door), a spiral tube is used (Fig. 5, b).
Rice. 5. Mounting accessories used when installing cabinets and consoles: a perforated box; b - spiral tube; c - seal; g - cable lug
Depending on the installation location and the corresponding degree of protection (IP), automation cabinets and panels must be equipped with input devices of the appropriate types.
Thus, for ordinary premises, it is sufficient to install a rubber seal on the outlet side of the cabinet (Fig. 5, c), in which a hole is cut for the supply pipe with a minus tolerance. For more severe operating conditions, special cable lugs are used (Fig. 5, d). The entire cabinet design must comply with the same conditions in terms of IP protection degree.
In Fig. Figure 6 shows general views of control panels for the ventilation and air conditioning system (with doors removed).
Rice. 6. General view of control panels for the ventilation and air conditioning system
Panels and consoles are installed on site after completion of all construction and basic finishing work, construction of cable channels, openings for cables and pipes, foundations and embedded metal structures.
The conditions for installing switchboards and consoles are determined by the projects, however, there are a number of general requirements that are provided for in SNiP 3.05.07-85:
· full-size cabinet and panel boards are installed only on supporting steel frames or on a concrete (brick) base;
· small-sized cabinet panels and modular panels are usually mounted on columns, walls, in openings and other building structures (wall-mounted) or on floor racks; fastening is carried out using bolts, the holes for which are located on the rear wall of the cabinet;
· the spatial position of panels and cabinets must be strictly vertical and horizontal;
· in the presence of vibrations, special shock-absorbing devices must be used at the installation site of switchboards and consoles;
· floors in the room where switchboards and consoles are located should not be electrically conductive;
· electrical wiring inputs into panels and control panels are carried out, as a rule, from below through rubber seals;
· the housings of metal panels and consoles are subject to mandatory grounding.
Group input of wires or cables laid in metal boxes, is carried out through a hatch, which is cut out in the wall of the panel during its manufacture.

INSTALLATION OF BOARDS, CONTROLS AND CABINETS
Before starting work on the installation of switchboards, consoles and cabinets, it is necessary to check the construction and technological readiness of the design mark; by this time, preparatory work must be completed, metal structures must be installed for the installation of small-sized switchboards and flat cabinets. Such metal structures include perforated, for example Z-shaped, profiles for installation on a wall; clamps for tying columns; stands for installation on the floor. The advisability of installing stands before attaching small-sized panels to them is determined by the installation conditions prevailing at a particular facility. The specified installation metal structures are fixed either on pre-installed embedded elements, or using SMP, plastic dowels or welding. Electrical and pipe wiring must be laid and brought to the installation sites of panel structures. The panels must be placed on the installation area so that the need for additional rigging work during their installation is eliminated.
The specific locations of panel structures determine their installation on various building foundations (Fig. 2.5). The features of the latter, as well as the design of the supporting parts of shields, consoles and cabinets, determine the method of their fastening (Fig. 2.6). There are two main methods of fastening: collapsible and non-dismountable, characteristic of most types of panel structures. For flat cabinets and auxiliary panels, a combined method is used, in which the supporting frame of the product is welded to the embedded elements, and the body of the product is fixed with threaded connections.
Panel structures must be delivered to the site in a form ready for installation, namely: with devices and installation products; with internal electrical and pipe wiring, prepared for connecting external circuits, as well as devices installed on site; with structures for installation and fastening of instruments, apparatus and electrical and pipe wiring; with fasteners for assembling and installing panel structures on site. The delivery set of the panel structure should include a passport, a general drawing with tables of connections and connections, and a key to the door lock.
Fig 2.5
Figure 2.6
During installation, panels, consoles and cabinets must be installed in a vertical position; before fastening, they must be aligned with level and plumb. The permissible deviation should not be more than 1° in any direction. Frames and auxiliary elements of composite panels must be fastened together with detachable connections. The gaps between the connecting surfaces should not exceed 2 mm per 1 m of length. The fastening of frames and auxiliary elements of adjacent panels, consoles, and cabinets to each other is carried out in two stages after alignment with level and plumb. At the first stage, preliminary alignment (using a bead) of the holes in the frame racks of adjacent panels and cabinets is performed. The ovality of the holes allows, without removing the bit, to insert a screw into the same hole, and then attach a nut for ShchPK, ShchSh shields and S cabinets; It is recommended to start this work with the holes on the rear pillars and the upper frame of the frame as the most accessible. At the second stage, after installing all the screws, they are tightened evenly.
Tightening of threaded connections is carried out using wrenches and screwdrivers. The use of universal tools (pliers, pliers, etc.) for these purposes is not permitted. Broken contact connections must be restored so that the quality of the restored connection is identical to the unbroken connection. It is also necessary to restore the paintwork if it is damaged during installation of the panel structure.
Upon completion of installation work, each panel, console or cabinet must be thoroughly inspected. During the latter process, it is necessary to check: the completeness of the panel structure; correct placement and fastening components between each other and to embedded elements; quality of installation and fastening of devices, installed cables and pipes. Panel structures are considered ready for commissioning if the full checks carried out give a positive result.
SELECTION OF ELECTRIC FURNACE POWER
The choice of power of an electric furnace for a bath is carried out in accordance with the volume of the room. As a rough guide for calculations, you can take the ratio of 1 kW electric furnace per 1 m3 of steam room up to 10 m3. For volumes above 10 m3, the following ratios are accepted: 0.75 kW per 1 m3. The indicated ratios are used for steam rooms with good thermal insulation. If the steam room has wall surfaces made of concrete, brick or stone, it is necessary to add about 1.4 m3 more to the calculated volume for each square meter of wall made of the specified materials.PREPARATION FOR INSTALLATION OF ELECTRIC FURNACE
Before installing the electric furnace, you must check the following:the voltage of the electric furnace and the control panel corresponds to the mains voltage; the control panel corresponds to the power and model of the electric furnace;
The power of the electric furnace corresponds to the volume of the steam room. The volume should not be lower than the minimum volume for the selected oven (see Instructions);
The maximum current of the fuses and the cross-section of the power cable are sufficient for the power of the furnace. (see instructions);
the location of the electric furnace allows for fireproof clearances around the furnace in accordance with the installation diagram;
The oven control device (thermostat and bath timer) is located on the easily accessible side. If necessary, the control panel can be moved by a qualified electrician to the desired side of the stove in accordance with the Instructions.
INSTALLATION OF AN ELECTRIC FURNACE IN A BATH
Wall-mounted option. The stove is attached to the wall in compliance with the recommended distances (see installation diagram). Lining cannot serve as a basis for mounting an electric furnace. It is necessary to install special power bars hidden behind the lining, which will ensure reliable fastening of the stove (up to 45 kg). Particular attention should be paid to the upper mounting screws - they carry the main load. When attaching to a brick wall, do not use plastic plugs.Floor option. When attaching the heater to the floor, it is necessary to take into account the minimum fire-safe distances to flammable surfaces of the bathhouse. It is possible to install the electric furnace directly on a wooden floor. The wall on the back side of the heater should not be lined with asbestos slabs, since such a coating causes a sharp increase in the temperature of the wall materials and also releases substances harmful to human health. The heater cannot be installed in a niche and there should not be a solid fence around it. Acceptable material for cladding walls and ceilings is lining made of softwood. Only one heater can be installed in the steam room.
INSTALLATION OF A REMOTE CONTROL PANEL (OK 3PS-3 remote control for the SKLE oven)
The remote control is mounted outside the steam room in a dry place on the wall of the bathhouse in accordance with the installation instructions. Deviation from the recommendations leads to a fire hazard.ATTENTION. There must be a passage at least 0.8 m wide in front of the control panel for maintenance.
TEMPERATURE SENSOR
The temperature sensor is mounted above the electric heater according to the installation instructions. Heat-resistant (up to 180°C) wires with a cross-section of 4x0.5 mm2 from the control panel (for example OK33PS-3 control panel) are connected to the sensor.ELECTRICAL INSTALLATION
Connecting the electric furnace and control panel to the electrical network can only be carried out by a qualified electrician. The necessary detailed connection diagrams are available in the installation and operating instructions, as well as on the inside of the control panel cover or the removable panel of an electric heater with built-in automation. The remote control can be connected semi-permanently using a rubber cable of the required cross-section, at least for medium loads.ATTENTION! The use of polyvinyl chloride insulated wiring to connect the heater to the network is prohibited due to its instability to high temperatures.
To connect the electric furnace, you must use a heat-resistant (up to 1800 °C) wire. All electrical appliances installed at a height of more than 100 cm from the floor must be approved for operation at a temperature of 125 ° C.
TEMPERATURE CONTROL
On the control panel (on the remote control) the desired temperature in the steam room is selected. A certain position of the handle corresponds to a certain temperature in the steam room. After that, by setting the clock mechanism to the desired position, the heating of the electric furnace is turned on for heating. A warning light (if installed) on the control panel indicates that heating is occurring. After using the steam oven, the electric stove is turned off by turning the clock mechanism knob to position 0, as a result of which the signal lights on the control panel go out, indicating that the heater is de-energized. If necessary, (forgot to turn it off), the clock mechanism of the switch itself will take care of automatically turning off the current. The bath heating temperature is set smoothly (stepless).OVERHEAT PROTECTION
If, in the event of a malfunction in the control system, the temperature reaches a value that is dangerous in terms of spontaneous combustion of wooden parts, then the temperature limiter located in the sensor or the thermostat fuse will completely cut off the electric furnace current. After the temperature has dropped to a normal level and the fault has been eliminated, the fuse can be returned to its working position (or replaced with a new one).TIMER
The timer serves as the main switch for the heater, works from the mains, with a setting range of 12 hours. Two timer scales, A and B, are selected by the switch installed on it (for OT2PS3, OK33PS3 remote controls).Scale A is temporary and is divided into two parts so that when you turn the switch clockwise, the heater heating range first follows (1-4 hours), followed by the waiting range until turned on (1-8 hours). Scale B does not have a waiting range; in this case, the heater heats up over the entire range (1-12 hours)
The current can be switched off from the heater before the set operating time by turning the clock mechanism counterclockwise to position 0.
SAFETY GUARD
It is recommended to install railings or handrails around the heater; they must be made in accordance with the minimum distances specified in the instructions.Made in Russia

4 SAFETY REQUIREMENTS
4.1 Persons with an electrical safety qualification group of at least third for electrical installations with voltages up to 1000V are allowed to connect and maintain the remote control.
Carry out maintenance of the remote control while it is energized;
Operate the remote control with the cover open;
Operate a faulty remote control;
Operate the remote control with a faulty electrical cable;
Installation and repair of the remote control by persons who do not have the appropriate qualifications;
Operate the remote control without grounding;
Use for grounding metal structures of water supply, heating and gas networks;
Operate the remote control without an electrical connection between the common point of all electric heaters and the neutral wire of the electrical network;
It is prohibited to use a load of more than 6 kW with a single-phase connection.
4.3 Installation of the remote control should be carried out in agreement with local authorities of the State Energy Supervision Authority.
4.4 Before starting operation, ground the console housing. The resistance of the grounding device must be no more than 10 Ohms.
4.5 Electric heaters are powered via a remote control in houses via lines independent from other electrical receivers, starting from apartment panels or building inputs, using a 25A circuit breaker.
5 DEVICE STRUCTURE
5.1 The remote control consists (see Fig. 1) of a housing (1), on which a terminal block (6), a grounding screw (8), an electromagnetic relay (7), an automatic switch (5), signal lamps (4) - heating are mounted and network, capillary thermostat with handle (3). The thermostat breaks the power supply circuit of the magnetic relays when the coolant heats up to the set temperature; when the temperature drops by 2-9°C, the thermostat closes the circuit and heating resumes. The remote control provides for the connection of an external channel for controlling the air temperature of the heated room. If it is absent, the “external channel” terminals on the terminal block are short-circuited (a jumper is installed).
5.2 When using the remote control to control water heaters CHAUS, EVP produced, emergency temperature limiter contacts are attached to the “external channel” terminals.
Air temperature regulators, including SMS thermostats, GSM switches with temperature control and other devices designed to control heating systems, can be used as an external control channel.
5.3. To control by air temperature using an external channel, it is recommended to set the temperature on the thermostat to 70-75°C.

6 INSTALLATION OF THE CONTROL PANEL
6.1 Install and secure the remote control permanently on the wall so that it can be easily accessed for repair and inspection. The distance between the remote control and the heating device is such that the thermostat cylinder can freely reach the special seat on the body of the heating device.
Insert the copper cylinder of the thermostat into a special seat on the body of the heating device. If the thermostat is installed on a device that does not have a seat for it, it is necessary to ensure that the thermostat is located in a blind sleeve flushed with coolant with an internal diameter of no more than 10 mm. This sleeve should be located in the upper (hottest) part of the heating device or nearby on the coolant outlet pipe from the heating device. To improve thermal contact, it is recommended to cover the cylinder with a layer of technical vaseline before installation.
Attention! The thermostat sensor is a copper cylinder connected to the thermostat by a capillary tube. Damage to the cylinder or breakage of the capillary tube leads to failure of the thermostat. When installing the control panel, you should handle the capillary tube carefully, avoiding unnecessary kinks.
6.2 All electrical connections must be made in accordance with electrical diagram remote control (see Fig. 2) and the designation on the XT1 terminal block.
Connect the cable from the heating elements EK1, ..., EK3 (heating elements are not included in the delivery package) to the terminal block (load) to terminals A2, B2, C2, N2.
Connect the cable from the distribution board (the cable and distribution cable are not included in the delivery) to the terminal block (input) to terminals A1, B2, C1, N1.
6.3 For a single-phase connection of the remote control, the phase wire must be connected to the combined jumper of the input contacts (A1, B1, C1) of the terminal block. In this case, the cross-section of the phase and neutral wires of the power cable must be at least 4 mm. It is prohibited to use a load of more than 6 kW with a single-phase connection.
6.4 Ensure that the console is grounded. Why attach a yellow-green grounding wire to the remote control grounding screw? Check the insulation resistance between the grounding clamp and each current conductor of the control panel; it should not be less than 1 MOhm.
6.5 After completing the installation, apply voltage to the remote control and the electric heater.
7 OPERATING PROCEDURE
7.1 Set the required temperature on the SK1 thermostat using the rotary knob of the thermostat.
7.2 Turn on the heating elements using the toggle switches “I”, “II”, “III” of the SF circuit breaker. Turning on toggle switch I is mandatory, since the remote control circuit is powered from it.
7.3 Each toggle switch connects 1/3 of the power. To turn off the remote control, set the circuit breaker knobs to the “OFF” position, and the “Network” and “Heating” indicator lights should go out.
