SECTION 4
OPERATION

     Ground Fault Detection

The PV-45208 is capable of detecting  PV array ground fault current. To enable this feature, a wire
must be installed between ground and the desired ground reference point on the PV array. For bipolar
PV array configurations, the ground wire must be connected between the PV array neutral point and
TB-NEUT terminal block. For grounded monopolar PV array configurations, the ground wire must be
connected between TBDC- and TB NEUT terminal blocks (see the following diagram for clarification
and the system schematic in Section 7). This feature is enabled for grounded monopolar PV array
configuration at the time of shipment. For bipolar PV array configuration, the jumper wire must be
removed between TBDC- and TB NEUT.
