

The diameter of a pole for installing an RRU ranges from 60 mm to 114 mm (2.36 in. to

4.49 in.). The recommended diameter is 80 mm (3.15 in.).



If the diameter of a pole ranges from 60 mm to 76 mm (2.36 in. to 2.99 in.), a maximum of three RRUs can be installed on the pole and the side-mounted installation must not be adopted.



If three or more RRUs must be installed on a pole in centralized mode, the diameter of the pole must range from 76 mm to 114 mm (2.99 in. to 4.49 in.).



The recommended pole thickness is 3.5 mm (0.14 in.) or thicker.



The angle between the vertical plane and the pole, angle steel, or U-steel must be smaller than or equal to 10°, as shown in Figure 3-5.

Installing an RRU on a Wall

The wall on which RRUs are installed must meet the following requirements:



When a single RRU is installed, the wall has a capacity of bearing at least four times the weight of the RRU.



Expansion bolts must be tightened with a torque of 30 N·m (265.52 lbf·in.) to ensure the bolts work properly and the wall remains intact without cracks in it.

3.5 Installation Clearance Requirements of an RRU

This section describes the requirements for the installation clearance of a single RRU and multiple RRUs and the requirements for the installation spacing between RRUs.

The recommended installation clearance ensures normal running and provides an appropriate space for OM. If there is sufficient space, leave the recommended installation clearance.

The minimum installation clearance ensures normal running and heat dissipation, but OM activities such as checking indicator status and opening the maintenance cavity cannot be properly conducted. If the installation space is restricted, leave the minimum installation clearance.
