1. Check cable connections and the
mechanical performance.
①
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.
②
Check that ground cables are properly connected.
2. Check the insulation only after the upstream and
downstream circuit breakers in the PDC are switched
off.
①
Switch off the upstream circuit breaker QFS for the SPD in the input module of the PDC, and
switch on other circuit breakers.
②
Check that the insulation resistance between the live wires, between the live wire and the PE,
and between the live line and the neutral wire is no less than 0.5 megohm using a multimeter.
③
After checking, turn off all the circuit breakers.
3. Switch on the SPD circuit breaker.
4. Switch on the input power
circuit breaker to power on
the PDC. If the power
indicator on the front panel of
the PDC lights up, the PDC
is powered on properly.
If the indicator of an SPD
module is green, the SPD
module is running properly. If an
indicator is red, the
corresponding SPD module has
failed and must be promptly
replaced.
The input power circuit breaker refers to the output circuit breaker that controls power supply from
the upstream power distribution equipment to the PDC.

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. User types are classified into admin and operator. User admin has higher operation rights than
user operator.
3. 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.
