Checking the Installation
Checking the Cables of RTN 320F
No.
Check Item
1
All outdoor connections and ground clips are moistureproofed or waterproofed.
2
The cable connectors are assembled correctly and securely.
3
Cables are not bent or twisted and the shield layer of the power cable is intact.
4
There is a drip loop in the cable after it leaves the RTN 320F.
5
There is a drip loop in the cable before it enters the equipment room.
6
The minimum bending radius of the cables is greater than 30 cm (11.8 inches).
7
Cables are placed tidily and are not cross-connected.
8
Cables are bound to the cable ladder or tray at intervals of approximately 1 m (3.28 feet).
9
Binding tapes are cut off with an excess section reserved at the ends.
10
Attach and bind cable labels correctly. Labels must be aligned and face the same direction.
The excess cable is coiled into a roll with a diameter not less than 60 cm (23.62 inches). The roll
11
is bound to the pole or the tower.
12
The cable ground point is properly protected.
13
The power cable does not bend in the range of 0.5 m (1.64 feet) above and below the ground clip.
The ground cable is routed from the top downwards and the angle between the ground cable and
14
other cables is less than 15 degrees.
15
The ground cable of the RTN 320F is properly connected.
16
The USB maintenance compartment is closed and screwed.
Checking the PI
No.
Check Item
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 the 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.
