● Switch operating instructions
Switch position, state and interlock
Operation steps：
Power transmission：Hang (close) the upper and lower doors with a circuit breaker (load switch) → the grounding switch with an isolating switch → the circuit breaker (load switch) with a power transmission is completed.
Power cut：Breaker (load switch) → disconnector → earthing switch → breaker (load switch) is unloaded (opened) and the door is blacked out.
