Installation Guide |
3 Information About the Installation |
This section describes RRU installation options. An RRU can be installed on a pole, U-steel, angle steel, or wall.
Installing an RRU on a Pole
Figure 3-4 shows the diameter of pole for installing an AAU3801.
Figure 3-4 Diameter of a pole
CAUTION
•The diameter of a pole for installing an RRU ranges from 60 mm (2.36 in.) to 114 mm (4.49 in.). The recommended diameter is 80 mm (3.15 in.).
•If the diameter of a pole ranges from 60 mm (2.36 in.) to 76 mm (2.99 in.), a maximum of two RRUs can be installed on the pole and the side-mounted installation is not recommended.
•If three or more RRUs must be installed on a pole in centralized mode, the diameter of the pole must range from 76 mm (2.99 in.) mm to 114 mm (4.49 in.).
Figure 3-5 shows an RRU installed on a pole.

CAUTION
•It is recommended that only one RRU be installed on U-steel.
•The vertical deviation angle of U-steel must be less than or equal to 10 degrees, as shown in
Figure 3-7.

CAUTION
•It is recommended that only one RRU be installed on angle steel.
•The vertical deviation angle of angle steel must be less than or equal to 10 degrees, as shown in Figure 3-7.
Figure 3-10 shows an RRU installed on angle steel.

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 to 30 N·m (265.52 lbf·in.) to ensure the bolts work properly and the wall remains intact without cracks in it.

NOTE |
|
|
|
|
|
|
|
|
|
|
|
The recommended installation clearance ensures normal running and provides an appropriate space for |
|
|
|
Operation and Maintenance (O&M). 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. |
This section describes the recommended and minimum installation clearance for a single RRU.
Recommended Installation Clearance for a Single RRU
Figure 3-13 shows the recommended installation clearance for a single RRU.
