Precautions
A three-phase AC switch needs to be installed on the AC side of the SUN2000. To ensure that
the SUN2000 can safely disconnect itself from the power grid when an exception occurs,
select a proper overcurrent protection device in compliance with local power distribution
regulations.
Do not connect loads between the SUN2000 and the AC switch directly connected to it.
The SUN2000 is integrated with a comprehensive residual current monitoring unit. Once
detecting that the residual current exceeds the threshold, the SUN2000 immediately
disconnects itself from the power grid.
