WIRING INFORMATION

Make sure the wiring is carried out by professionals who have a proper understanding of this manual.
Before wiring examine the switch to ensure that it is undamaged. Operate the switch using the operating handle and use a multimeter to check that all phases of the active (standby) power and load connection/disconnection are normal.
When wiring pay special attention to the following :
a. The phase sequences of the active and standby power should be verified to be the same.
Verify that the voltage of the active and standby control power are both 220VAC.
b. Perform the wiring according to the labels that identify the wiring terminals of the main circuit and the control circuit.
c. Ensure the switch is grounded properly.
Use the operating handle only for switch debugging and maintenance in the power off. Do not use the operating handle with a load. The handle should be removed before the switch is under power.
