The positions for laying out power cables should be in accordance with the design
drawing.
If the cable length is insufficient, use another power cable with a sufficient length. No
joint or weld is allowed on a power cable.
Power cables must be routed by only qualified and trained personnel after all
preparations are made.
Power cables are straightly routed and not twisted or winded.
Ground cables in a base station should be connected to the same ground bar.
Ground cables must not be routed in from the overhead. They must be routed
underground or indoors.
Both ends of the external conductor of a coaxial cable and the shield layer of a shielded
cable should have good electrical contact with the metal shell of the device they connect
to.
Ground cables and signal cables should be bound separately with a proper distance in
between to avoid interference.
Circuit breakers or fuses are not allowed on ground cables.
No devices can be used as a part of ground cables.
All conductive metal components in the shell should properly connect to protection
ground terminals.
