The ground point on the enclosure is preferred to connect to the PE cable for
the SUN2000. The ground point in the maintenance compartment is used for
connecting to the PE wire of a multi-core AC power cable.
It is recommended that the SUN2000 be connected to a nearby ground point.
For a system with multiple SUN2000s connected in parallel, connect the
ground points of all SUN2000s to ensure equipotential connections to PE
cables.
A three-phase AC switch should 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.
The SUN2000 is integrated with a comprehensive residual current detection
unit to distinguish fault current from residual current. Upon detecting that the
residual current exceeds the threshold, the SUN2000 immediately disconnects
from the power grid.
