Checking Cable Installation

6.3
No. Check Item
All bolts are tightened, especially the bolts used for electric connection.
1
Flat washers and spring washers are installed properly.
2
Check whether the cable installation meets requirements.
Cables are routed in a way convenient for maintenance and capacity
3
expansion.
4 There is no unnecessary adhesive tape or cable tie on cables.
Exposed parts of wires and cable lugs near the wiring terminals are
5
wrapped by insulation tape or heat shrinking tubing.
The routing of power cables and monitoring cables meets the
6 requirements for routing signal cables and power cables and complies
with the cable routing planning.

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.
(Optional) UPS Input and Output 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.
1. Before manual operations,
2. If the motor mode is to be
If the SPD module indicators
are green, the SPD is running
properly. If an SPD module
indicator is red, the SPD
module is faulty and must be
replaced immediately.
