Precautions for operating the isolating switch

(1) Before operation, check that the circuit breaker (switch) is in the open position to prevent the isolation switch from being pulled and closed with load.

(2) A blocking device to prevent misoperation is installed between the knife switch, the grounding knife switch and the switch, and the switching operation must be carried out in sequence. If it is blocked and cannot be operated, the reason should be found out. Under normal circumstances, it cannot be unlocked at will.
