The recommended installation space meets the requirements of the equipment for normal running and OM. When the installation space is sufficient, the recommended installation space can be adopted.
The minimum installation space meets the requirements of the equipment for normal running and heat dissipation, but does not meet the requirements for OM such as checking the status of the indicators and opening the maintenance cavity. When the installation space is restricted, the minimum installation space can be adopted.

The angle between the vertical and the angle steel or U- steel or angle steel where the RRU is
≤10° installed must be less than or equal to 10 degree.
zThe RRU must be supported by foam or cardboard for protection.
zThe RF ports at the bottom of the RRU cannot bear the weight of the RRU. Do not place the RRU on the ground in the upright position.
a Installing the RRU on a Pole
[Diameter: 60 mm (2 3/8'') to 114 mm (4 1/2'')]
1. Install the main bracket.
When installing the main bracket, ensure that the contact piece on the bracket is fixed.
1200 mm (3'-11 1/4'') to 1600 mm (5'-3'')
Main bracket
Spring plate
60 mm (2 3/8'') to 114 mm (4 1/2'')
The recommended diameter of the pole is 80 mm (3 1/8").
You may fit one end of the auxiliary bracket on one dual-nut bolt assembly and then the other end on the other dual-nut bolt assembly during the installation.

2. Use an adjustable wrench to tighten the nut until the fastening torque is 40 N.m (354.03 lbf.in.). This secures the main and auxiliary brackets to the pole.
40 N.m
(354.03 lbf.in.)
Tighten the two dual-nut bolt assemblies alternatively. After the brackets are secured, use a measuring tape to measure the spacing between the main bracket and the auxiliary bracket on two sides and confirm that the spacing is the same.
3. Install the RRU on the main bracket. When you hear click sound, the RRU is securely installed.
b |
Installing Two RRUs on a Pole |
|
[Diameter: 60 mm (2 3/8'') to 114 mm (4 1/2'')] |
||
1. Install the first RRU. |
2. Install the second main bracket. |
The arrows on the main bracket point upwards.
