Ground fault enable (JP3)
JP3 is used to set the NAC/AUX circuits for ground fault enabled or disabled
operation. The sense inputs are always isolated from local power.
Enabled: Allows the BPS to perform its own ground fault checking. This is the
default position.
Disabled: Disable the BPS's ground fault detection only when the controlling
panel is providing ground fault detection for the BPS output circuits. See
Figure 8 on page 13 for wiring information.
