Explosion-proof road lights are ideal for fixed lighting applications in low-light environments, especially in hazardous areas such as oil refineries, chemical plants, metal processing facilities, railway stations, power generation sites, ships, offshore oil platforms, and other industrial installations. These lights are designed to provide safe and reliable illumination in potentially explosive atmospheres. Here's how they should be used:
Explosion-proof road lights are suitable for fixed lighting applications at night in various industrial settings, including petroleum, petrochemical, metallurgy, railways, power plants, ships, offshore oil platforms, and chemical installations. The installation and usage process is as follows:
Based on the actual lighting needs of the work site, determine the position and method for installing the lamp and ballast. Measure the distance between the lamp's contact point and the ballast, and from the ballast to the 220V power source. Prepare a three-core cable of appropriate length (no more than 2 meters is recommended with the lamp’s built-in cable).
Close the ballast box cover and tighten the fastening bolts securely. Then, connect the other end of the three-core cable to the 220V power supply, following the required explosion-proof installation standards.
If the distance between the explosion-proof road light and the ballast exceeds 2 meters, replace the three-core cable. Use an Allen wrench to remove the six hexagonal bolts on the lamp housing. Pull out the lamp body, take out the original three-core cable, and connect the newly prepared three-core cable using the same wiring method.
Feed one end of the prepared three-core power cable through the input device of the ballast. Insert it into the ballast cavity, then connect the live wire (L), neutral wire (N), and ground wire (PE) to terminals 1, 2, and 3 respectively. Tighten the compression nut securely.
Use a socket wrench to unscrew the fastening bolts on the ballast cover and remove the cover. Feed the lamp’s three-core cable through the ballast output device. Connect the red wire to terminal 4, the black or blue wire to terminal 5, and the yellow-green wire to terminal 6. Then, tighten the compression nut properly.
When replacing the bulb, first turn off the power to the explosion-proof road light. Check that the hanging chain is secure. Use an Allen wrench to loosen the six hexagon socket bolts on the lamp housing. Carefully lower the lamp body to separate the lamp cap, then remove the old bulb and install a new one of the correct type and wattage.
These steps ensure proper installation and maintenance of explosion-proof road lights, helping to maintain safety and efficiency in high-risk environments. Always follow manufacturer guidelines and local regulations when handling electrical equipment in hazardous areas.
