AC Power Test
Purpose/Scope
This procedure explains how to check the AC power at the PEP.
Parts
None.
Tools
•
Digital multimeter (DMM).
Safety Considerations
Procedure
□
1. Switch the main power switch on the PEP to the OFF posi-
tion. Figure
PR16-1 shows the PEP.
□
2. Unplug all of the line cords from the AC outlets on the PEP.
□
3. Switch the main power switch on the PEP to the ON
position.
□
4. Use the DMM, set to measure AC RMS voltage, to measure
the voltage at each of the AC outlets. The line voltage should be
90 to 132 VAC RMS for a 120-VAC input and 180 to 264 VAC
RMS for a 240-VAC input.
□
5. Use the DMM to check each AC outlet to insure that neu-
tral, live and ground are correctly wired, and that there are no
ground faults.
□
6. Switch the main power switch on the PEP to the OFF
position.
□
7. Use the DMM to verify that there is no power to any of the
AC outlets.

WARNING
1. There are exposed AC and DC connections inside the cabi-
net. These exposed electrical connections present a shock
hazard that can cause injury or death.
