Maintenance
There is no required maintenance schedule for the Z-PDS; however,
toggling on/off all the output circuit breakers to ensure all the LEDs
illuminate during general maintenance windows or when the Z-PDS is
not in use will help ensure all output branch circuits are working
correctly.
Troubleshooting
The Z-PDS is designed and tested for the highest reliability possible.
Problems encountered with improper voltages or in-active circuits
will generally be attributed to an abnormal condition of the branch
circuit delivering the source power to the Z-PDS. If any condition
exists that would indicate a problem, follow this process:
1. Check the source power whip or busway tap box circuit
breakers. Check that the 3-pole circuit breakers feeding the
Z-PDS are fully closed. Toggle to ensure position and check
the LED indicators on the Z-PDS to ensure that input power
is being delivered.
2. Use a suitable voltmeter and test for the following. This test
should only be done by a qualified electrician or qualified
technician.
a. Verify inter-phase voltage (X-Y, X-Z, Y-Z)
b. Verify phase to neutral voltages
c. Verify 0.0 Volts from neutral to ground
d. Verify less than 1ohm from neutral to ground
3. If any fault is located with the A-B feed circuits to the Z-PDS,
have a certified electrician correct it.
