Disabling Ground Fault Protection for Negative Grounded and Ungrounded Arrays
To install the XW SCC in a system where an external negative-ground bond is required or
where the PV array must not be grounded, the XW SCC internal PV-GFP circuit and
ground bond must be disabled. To disable the unit’s PV-GFP circuit and ground bond,
move the jumper connector located on the circuit board within the wiring compartment.
See Figure 4-7.
Disabling the PV-GFP circuit in this way opens the negative-to-ground bond within the
unit. This provides the option of using an external PV-GFP circuit, operating the XW SCC
with an ungrounded PV array, or grounding the negative circuit of the battery elsewhere in
the system.

WARNING: Shock Hazard
Disconnect PV and battery circuits before removing the grounding connection or before removing
or installing the PV-GFP fuse.

WARNING: Fire Hazard
Ensure there is no other ground connection in the DC
wiring or the PV-GFP will be defeated and will not
protect the array from ground fault conditions.
WARNING: Shock Hazard
Disconnect PV and battery circuits before accessing the XW SCC wiring compartment.
