WIRING INSTRUCTIONS OF MOTORIZED EARTHING SWITCH

1. When switch equipment motorized control device terminal No. 3 and No. 4 corresponds to terminal No. i positive and No. 2 cathode, be careful not to reverse the polarity of the power supply to avoid damage to the motor. Through the debugging to observe whether the rotates direction of earthing switch operating shaft gear met the switch’s opening, closing state, otherwise swap the positive and negative

2.If operate motorized earthing switch separately(not loading), switch equipment motorized control device terminal No. 11 and No. 10(0V common terminal) short.
