3-1-1. Power ON / OFF / REMOTE (Main) switch:
a. Before installing the inverter, you need to ensure the main switch
is in the OFF position.
b. Before using the remote unit, you need to ensure the main switch
is in the REMOTE position.
3-1-2. AC input Circuit Breaker:
The AC input circuit breaker protects the model from overload.
When an overload condition exists, the circuit breaker stops to supply
output AC grid power. To reset it, push the circuit breaker switch
then the model will be back in normal operation. The source fault
should be corrected before you reset it.
