How to connect the explosion-proof emergency light of gas station ?
70wled gas station explosion-proof emergency light wiring method:
1. The common lighting lamp has three wires and three colors like the emergency lamp:
a, purple (red): FireWire
b. Black: zero line
c. Blue: switch wire
Before wiring, we want to ask Chu, whether we only use it in an emergency, or when we do not need an emergency.
1. Use the wiring method only in emergency: connect the live wire and the neutral wire.
2. Use the explosion-proof emergency light wiring method of the gas station when no emergency is needed: connect the switch wire and the live wire to the same live wire, install a switch on the switch wire, the zero wire is still connected to the zero wire The incoming line still has only one live line and one neutral line.
