8.5 Installing the RRU on a Wall
This section describes the procedure and precautions for installing the RRU on a wall.
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.
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 anchor bolts must be tightened to 30 N·m (265.52 lbf·in.) so that the bolts stay
secured without damaging the wall.
Procedure
Step 1 Disassemble the RRU mounting brackets, as shown in Figure 8-34.
