Startup sequence

1. Turn the circuit breaker on the AC side to the "ON" position;

2. Turn the DC switch of the inverter to the "ON" position.

Shutdown sequence

1. Turn the circuit breaker on the AC side to the "OFF" position;

2. Turn the DC switch of the inverter to the "OFF" position.

If the startup and shutdown sequences given above are not followed strictly, the
inverter may be damaged.

8.3 Electrical Connection Check

1. Check whether the cable connection is loose;

2. Check whether the grounding cable is reliably grounded;

3. Check whether the waterproof covers for RS485, WiFi and other ports are sealed correctly.

Note: The maintenance cycle is once every six months.
