1. Based on the actual lighting needs of the work site, determine the installation location and method of the lamps and ballasts, and then prepare corresponding lengths of three core cables according to the distance from the lamps to the ballast contact and the distance from the ballast to the 220V power supply contact (the cables provided with the lamps can be used if the distance does not exceed 2 meters).

2. When the distance between the lamp and the ballast contact exceeds 2 meters, it is necessary to replace the three core cable. Use an Allen wrench to unscrew the six Allen bolts on the lamp housing, pull out the lamp body, remove the three core cable that comes with the lamp, and then connect the prepared three core cable according to the original wiring method.

3. Use a socket wrench to unscrew the fastening bolts on the ballast box cover, remove the box cover, and introduce one end of the three core cable of the lamp into the ballast chamber through the introduction device of the ballast output port. Connect the red wire, black wire (or blue wire), and yellow green wire to the 4th, 5th, and 6th terminals of the ballast, and then tighten the compression nut.

4. Insert one end of the prepared three core power cable through the input device of the ballast into the ballast chamber, and then connect the L wire (live wire), N wire (neutral wire), and ground wire to the wiring terminals of positions 1, 2, and 3 of the ballast, and tighten the compression nut.

5. Close the ballast box cover and tighten the fastening bolts, then connect the other end of the three core cable to a 220V power supply according to explosion-proof requirements.

6. When replacing a light bulb, first cut off the power supply, check if the suspension chain is properly hung, and then use an Allen wrench to unscrew the six Allen bolts on the lamp housing. Carefully pull down the lamp body to separate it from the lamp head housing. Unscrew the old bulb and replace it with a new one.
