Led explosion-proof light according to the needs of the work site to determine the installation location and method
Led explosion-proof light use method:
1, led explosion-proof lights According to the actual lighting needs of the work site, determine the lamp installation location and method, and then press the lamp to 220V power contact distance to prepare the corresponding length of Φ8 ~ 14mm three-core cable.
2. Remove the side panel with "open/lock" mark on the junction box. Take out the mounting accessories from the box, including sealing ring, gasket and connector (with set screw). If the lamp is installed by ceiling, then There are ceiling type adapters (with set screws) and 3/4 inch adapters.
1) Wall-mounted installation: firstly install the lamp body on the wall or other supports through the bracket (guarantee that the shading plate is directly above the bulb), then pass the cable through the connector, gasket and seal ring until the junction box (reserved) A certain length of cable is convenient for wiring). Finally, tighten the joint and tighten the set screw;
2) Led explosion-proof lamp tilted boom installation: the joint through the cable, screw into the steel pipe, tighten the set screw, and then the cable through the gasket, seal ring until the junction box (reserve a certain length of cable is convenient Wiring), and then screw the lamp body into the connector, must ensure that the terminal box wiring port is facing down. After connecting the wire according to the third step, adjust the relative position of the copper joint and the steel pipe to ensure that the shading plate is directly above the bulb, and then tighten the set screw;
3) led explosion-proof light vertical boom type installation: first through the cable connector, screw into the steel pipe, tighten the set screw, and then the cable through the gasket, seal until the junction box (reserved a certain length The cable is convenient for wiring), then tighten the lamp body and connector, and tighten the set screw;
4) Ceiling mounting: Screw the 3/4 inch adapter into the ceiling adapter, screw in the 3/4 adapter, tighten the set screws, pass the cable, install on the roof, and finally turn the cable Through the gasket, seal ring until the junction box (reserve a certain length of cable to facilitate wiring), then tighten the lamp body and connector, tighten the set screw;
3. Connect one end of the three-core cable to the “Lâ€, “N†and grounding marks in the box, and then press the cable with the cable clamp and fix it with the fastening screw. Then attach the side plate and tighten the screw. .
4. Finally, connect the other end of the three-core cable to the 220V power supply according to the explosion-proof requirements.
5, when replacing the bulb, first cut off the power, then use the Allen wrench to remove the set screw on the shell, use a large screwdriver or other tools to loosen the lamp cover 6 circles, and then carefully remove the lamp cover by hand, rotating Replace the old lamp with a new one.
Led explosion-proof lights note:
1. When the LED explosion-proof lamp fixture is installed obliquely, the relative position of the joint and the steel pipe must be adjusted to ensure that the shading plate is directly above the bulb;
2, led explosion-proof lamp installation and maintenance of lighting, must first cut off the power;
3, when used, the surface of the lamp has a certain temperature rise, which is a normal phenomenon. The center temperature of the transparent part is relatively high and must not be touched.
4, must use the company equipped with electrical appliances;
5, led explosion-proof lamp replacement bulb, should use the same type, power bulb; if you change the bulb type or power, should replace the corresponding ballast.
