Power-On Commissioning

NOTICE
1. The power-on commissioning personnel must be at least two qualified electricians. One performs
operations while the other monitors the operations. Irrelevant persons should be warned off.
2. Powering off the PDC disconnects the power supply to the downstream devices. Exercise caution
with this operation when the PDC is supplying power to a working system.
3. If the power indicator on the front panel of the PDC lights up, the PDC is powered on properly.
1. Check cable connections and the mechanical performance.
•
Check that cables are connected correctly outside the cabinet. Check that all bolts are
secured for 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.
