(Optional) UPS Input PDC Power-On Commissioning
1. Check cable connections and the mechanical performance.
Check that cables are connected correctly outside the

cabinet. Check that all bolts are secured for inlet and outlet
cables and tighten a bolt if it is loose.
Check that ground cables are properly connected.

(Optional) Switch on and off all circuit breakers and ATSs

three times. Ensure that they can be switched on and off
smoothly.
2. Check the insulation.
Switch off the upstream circuit breaker QFS for the SPD

in the PDC, and switch on other circuit breakers, as shown in
the figure.
(Optional) Flip the ATS to I or II.

Check that the insulation resistances of the power

distribution devices and feed circuit are no less than 0.5
megohm.
After checking, turn off all the circuit breakers.

3. Turn on the upstream circuit breaker of the PDC. If all the
input indicators light up at the same time, the PDC input
power is normal.
4. Verify that the phase sequence of the input power is
correct using a phase sequence meter. In the ATS input
scenario, check the phase sequences of both power
inputs.
5. Turn on the upstream switch of the SPD.
6. Turn on the input circuit breaker of the PDC and check
whether the voltage and frequency on the electric meter
are normal.
7. The PDC power-on check is completed.
