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.
