Determine the positions where the clips are installed according to the actual situation.
For example, 7/8" feeders are secured with clips at an interval of 1.5 m (4.92 ft) to 2 m
(6.56 ft), and CPRI fiber optic cables and power cables are secured with clips at an
interval of 1 m (3.28 ft) to 1.5 m (4.92 ft). Ensure that the clips are evenly spaced and in
the same direction.
When fastening cables with a clip, ensure that the cables are aligned neatly and are
routed through the holes in the clip. Do not stretch the cables too tightly.
When using clips to secure cables, tighten the screws on the clips after all cables are
arranged and laid out.
PGND cables for a base station must be connected to the same ground bar.
PGND cables must be buried in the ground or routed indoors.
The external conductor of the coaxial wire and the shield layer of the shielded cable must
have proper electrical contact with the metal surface of the equipment which they are
connected to.
PGND cables and signal cables must be installed separately. A certain distance must be
reserved between them to prevent interference from each other.
Switches or fuses must not be installed on the PGND cables.
Other devices must not be used for electrical connections of the PGND cables.
All the metal parts in the housing of the equipment must be reliably connected to the
ground terminal.
