5.2.2 JP9 (Earth Ground Detect)
This jumper allows disabling of the Earth Ground Fault detection for applications that either don’t
require Earth Ground Fault detection, or for applications where Earth Ground Fault detection is
already provided by other equipment.
5.2.3 JP5, JP6, JP7 (Buss 1 / Buss 2)
The fuse associated with JP5, JP6, and JP7 determines whether the output of the PS5-M connects
to Buss 1 or Buss 2 of the ABC connector. See Figure 3.7.1
Fuse between JP5 and JP7 connects the PS5-M to Buss 1
Fuse between JP5 and JP6 connects the PS5-M to Buss 2

Description
LED
5.3.1 AC ON (D19)
For safety reasons, this LED illuminates any time there is AC voltage present at the AC input,
regardless of the AC fault status, battery state of charge, or power supply condition.
CAUTION - Always check for AC presence with an AC volt meter before servicing
5.3.2 DC OUT (D15)
This LED illuminates when DC voltage is available at the DC+/DC- terminals.
5.3.3 AC FLT (D22)
This LED illuminates when the AC input voltage falls below approximately 85% of the nominal
input voltage setting.
5.3.4 COM FLT (D16)
This LED illuminates on any of the following conditions:
High or Low Battery Voltage
High or Low Output Voltage
Missing Battery or blown battery fuse (optional)
Earth Ground Fault (optional)
Internal fault
5.3.5 GND FLT (D21)
This LED lights whenever there is an Earth Ground Fault
