7.5 Installing the RRU on a Wall
This section describes the procedure and precautions for installing the RRU on a wall. An RRU
on a wall is installed in standard mode by default.
Prerequisites
The hoist clamp on the main bracket is secured properly.
NOTICE
l
Do not stand the RRU upright because the RF ports cannot support the weight of the RRU.
l
Place a foam pad or cardboard under the RRU to protect the RRU housing from damage
during the installation.
l
When installing RRUs on a wall, do not combine the mounting brackets for multiple RRUs
together.
Context
The wall on which RRUs are installed must meet the following requirements:
l
For each RRU, the wall must be able to bear a weight four times the RRU's weight and the
bolts' pulling force of 1.25 kN (281.25 lbf) vertical to the wall.
l
Expansion bolts must be tightened to 15 N·m (132.76 lbf·in.) so that the bolts stay secured
without damaging the wall.
Procedure
Step 1
Remove the plastic cap, M10 nut, spring washer, thick flat washer, auxiliary bracket, and
M10x150 bolt one by one. Reserve the main bracket for the wall-mounted installation.
Step 2
Place the main bracket against the wall, use a level to verify that the main bracket is placed
horizontally, and use a maker to mark anchor points, as shown in
RRU3942&RRU3642
