Examine the AC power cord for the power supply and then check if there is any splits or cracks
in the insulation.
2. Replace power cord if needed.

be required for replacing the cord.
3. (If present) Check the condition of MOV’s installed for cracks and/or burn spots in the devices
and then replace if needed.
4. Measure the AC input voltage and record the value.
5. (If UPS power is used) Check the quality of the AC waveform (that is, ensure that the waveform
is within manufacturer’s specifications).
Distortion:
Utility mains power normally has less than 5 % harmonic distortion.
Transformer of proper rating adds about 1 % distortion.
Total Harmonic Distortion (THD) of 6 % is acceptable.
Maximum THD acceptable is 8 %.
6. Check the red and black DC power wires connected to each power supply for
l signs of corrosion in the power wires,
l splits or cracks in the insulation, and
l loose connections on each end of the wires.
7. Inspect the red and black DC power wires connected between each cabinet (in a cabinet

l AC Safety Ground to the AC Safety Ground rod.
Inspect how the wire from AC Safety Ground in the cabinet routed to the AC Safety Ground
collection plate.
10. a. Inspect the ground wire for MRG.
b. Inspect whether a 4 AWG (5.3 mm) or larger wire used to connect the local reference bar
with the MRG ground rod.
c. Check for loose connections at each end of the wire
11. Check how is the wire from the local reference bar to the MRG ground rod routed.
12. Inspect whether the wire from the local reference bar to the MRG ground rod is exposed
anywhere.
13. Measure the voltage difference between MRG and AC Safety Ground for each cabinet using a
.
