No.
What to Check For
1
All the self-made PGND cables are copper-based with proper wire diameters. There is no
switch, fuse, or short circuit on the cable.
2
According to the wiring diagram of the power system, the PGND cables are connected securely,
the AC lead-in cables and cables inside the cabinet are connected properly, and the screws are
tightened. Ensure that the output and input cables are not short-circuited.
3
The redundant part of the power cable or PGND cable is stripped off rather than being coiled.
4
The lugs at both ends of the power cable or PGND cable are soldered or crimped securely.
5
Bare wires and lug handles at the wiring terminals are wrapped tightly by using insulation tapes
or heat shrink tubings.
6
The flat washers and spring washers are mounted securely to all the wiring terminals.
7
The connectors of all cables are securely linked, especially those at the bottom of the cabinet.
8
The cables are properly bound. Cable ties are installed at equal spacing and in the same
direction.
9
The power cable and PGND cable are routed separately from other cables.
10
The cable layout facilitates maintenance and expansion in the future.
11
The labels at both ends of each cable are legible.
12
The excess of cable ties is trimmed off without remaining rough edges.
