The explosion-proof road lamps can work safely in flammable and explosive places, and are used for various indoor work sites, petrochemical installations, operations, and offshore oil platforms, railways, iron and steel, fire protection, and government agencies.
How to use explosion-proof road lights
1, according to the actual lighting needs of the work site, determine the lamp and ballast installation location and method, and then press the lamp to the ballast contact point distance and ballast to the 220V power contact point to prepare the appropriate length of the three-core cable Line (a cable with a lamp is not more than 2 meters away).
2. When the distance from the lamp to the ballast contact exceeds 2 meters, the three-core cable needs to be replaced. That is, use an Allen wrench to unscrew the six hexagon socket bolts of the lamp housing. After the lamp body is pulled out, remove the three-core cable that comes with the lamp, and then connect the prepared three-core cable according to the original connection method.
3. Use a socket wrench to unscrew the fastening bolts on the ballast cover and remove the cover. Introduce one end of the three-core cable of the lamp into the ballast cavity through the introduction device of the output port of the ballast and put the red wire. The black line (or blue line) and the yellow-green line are respectively connected to the ballast's terminals 4, 5, and 6, and then the compression nut is tightened.
4. Introduce one end of the prepared three-core power cable through the input device of the ballast input port and introduce it into the ballast cavity. Then, connect the L line (FireWire), N line (neutral line), and ground line to the ballast. On the terminals of terminals 1, 2, and 3, and tighten the compression nut.
5. Close the ballast cover and tighten the fastening bolts. Finally, connect the other end of the three-core cable to the 220V power supply in accordance with the explosion-proof requirements.
6. When replacing the bulb, first cut off the power supply and check whether the hanging chain is hanging. Then use a hexagon socket wrench to open the six hexagon socket bolts on the lamp shell. Carefully pull down the lamp body part to separate the lamp body from the lamp cap shell. Unscrew the old bulb and replace it with a new one.
Explosion-proof road lights considerations
1. When installing and maintaining the lamp, the power must be cut off.
2. When using, there is a certain temperature rise on the surface of the lamp, which is a normal phenomenon. The center temperature of the transparent part is relatively high and must not be touched.
3, must use the company's equipped ballast.
4, the lamp starting current is 2.5 times the normal operating current, 250W lamp starting current is 2.8A.
5. Shock-absorbing foam is installed inside the lamp cap and it must be removed when it is installed for the first time.
