Appendix
Checking the Installation
9
Check the installation.
No.
1
The PI installation position meets the requirements specified in engineering design documents. The
PI is installed securely.
2
The appearance of PI components is in good conditions. If there are any paint peeling-off, bump
marks, or smears, repaint or clean the components.
3
Cables are routed in compliance with engineering design documents, which facilitates maintenance
and capacity expansion.
4
Cable connectors are assembled in compliance with specifications. They are installed securely.
5
Cables are not bent or twisted. The shield layer is not exposed.
6
Drip loops are made after cables are routed out of the PI.
7
Drip loops are made for cables near a room inlet.
8
The minimum bending radius of cables is greater than 30 cm (11.8 inches).
9
Cables are installed in an untangled and orderly fashion.
10
When binding cables on the cable ladder or cable tray, ensure that the spacing between cable ties
does not exceed 1 m (3.28 ft). It is recommended that the first binding point be no more than 0.5 m
away from the module and be bound with two cable ties.
11
An excess of cable ties is reserved.
12
Cable labels are attached or bound according to related requirements. The labels are arranged
neatly and face the same direction. It is recommended that a label be attached to a cable position 2
cm away from the connector.
13
Redundant cables are coiled into a roll with a diameter of 60 cm (23.62 inches) or larger and then
bound to the pole or tower.
14
Cable ground points meet requirements.
15
A cable is not bent within a range of 0.5 m (1.64 ft) above and below the ground clip.
16
Ground cables are routed from the top downwards, and the angle between ground cables and
other cables is less than 15 degrees.
17
PI ground cables are correctly connected.
