Connect the three-phase electricity to the ground wire. All wiring activities should be carried out under the condition of power failure!
The wireless remote controller consists of a remote control transmitter and a remote control receiver, which are used in pairs. The remote transmitter sends an operation instruction, and the remote receiver receives the operation instruction and controls the relay (contactor) to act.
The red wire is connected to the main contactor coil, the yellow-green wire is connected to the "upper" and "lower" contactors, the green-blue wire is connected to the "east" and "west" contactors, the gray-white wire is connected to the "south" and "north" contactors, and the pink wire is the spare wire. Don't worry.
