•
Do not connect loads between the inverter and the AC switch directly connected to the
inverter.

The Residual Current Monitoring Unit (RCMU) is integrated into the inverter. The inverter
will disconnect the utility grid rapidly once it detects any leak current over the permissible
range.
An AC circuit breaker shall be installed on the AC side to make sure that the inverter can safely
disconnect the grid when an exception happens. Select the appropriate AC circuit breaker in
compliance with local laws and regulations. Recommended AC circuit breakers:
