7.2.1 Installing a Single RRU
This section describes the procedure and precautions for installing a single RRU on a pole. A
single RRU can be installed on a pole in standard or side-mounted mode.
Prerequisites
Before you install an RRU on a tower, the RRU and mounting brackets are hoisted onto the
tower. For details, see 6.1 Hoisting an RRU onto a Tower.
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.
Procedure
Step 1 Determine a position for installing the mounting bracket.
l If the RRU must be installed on a pole secured on a tower, see 3.5.1 Clearance for a Single
RRU to determine a position.
l If the RRU must be installed on a pole secured on the ground, see Figure 7-3 to determine
a position.
Figure 7-3 Distance between the mounting bracket and the ground
NOTE
It is recommended that the mounting bracket be 1,200 mm (47.24 in.) to 1,600 mm (62.99 in.) above
the ground.
Step 2 Loosen the two M10 nuts on the mounting brackets and move the M10x150 bolt out of the trough
on the auxiliary bracket, as shown in Figure 7-4.
