Installation Options
The following figure describes the specifications for the metal pole, angle steel, and U-steel where the RRU is
installed.
Metal pole Angle steel U-steel
The brackets cannot be
combined when the RRUs
are installed on the wall.
zA maximum of two RRUs can be installed on a metal pole with a diameter of 60 mm [2.4 in.] to 75 mm [3 in.] ,
and the installation mode must be standard mode. Three or more RRUs must be installed on a metal pole with
a diameter of 76 mm [3 in.] to 114 mm [4.5 in.] in a centralized way.
zIt is recommended that only one RRU be installed on a U-steel or an angle steel.
zWhen installed on a tower, one RRU can be installed only in standard mode or reverse mode rather than
side-mounted. Two RRUs cannot be installed in back-to-back mode.
The angle between
the vertical and the
angle steel or U-
steel or angle steel
where the RRU is
installed must be
less than or equal
to 10 degree.

When installing the
main bracket,
ensure that the
contact piece on
the bracket is fixed.
You may fit one end of the auxiliary bracket on one dual-nut bolt assembly and then the other end on the
other dual-nut bolt assembly during the installation.
Fasten the two dual-nut bolt assemblies
alternatively. After the brackets are secure,
use a tape to measure the spacing between
the main bracket and the auxiliary bracket at
the two sides and ensure that the spacing is
the same.
zThe weight-bearing capacity of the RF
ports at the bottom of the RRU is low. Do
not place the RRU at its bottom.
zDuring the operation, place the foam
pad or cardboard under the RRU to
prevent any damage to the housing of
the RRU.
2. Use an adjustable wrench to tighten the nut until the fastening torque is 40 N·m [354
lbf•in.]. In this way, the main and auxiliary brackets are secured on the pole.

Installing the RRU on a Wall
1. Place the auxiliary bracket at the installation position. Use a level to check that the
auxiliary bracket is placed horizontally. Then, mark the anchor points by using a
marking pen.
zIt is recommended that the auxiliary bracket be 1,200 mm [47.2 in.] to 1,600 mm [63.0 in.] above the ground.
zThe RRUs cannot installed on a wall in centralized mode. Therefore, expansion bolt assemblies should be
prepared for each RRU.
2. Drill holes at the anchor points and then install the expansion bolt assemblies.
When the RRU is installed on a wall, the requirements are as follows:
zFor one RRU, the wall has a weight-bearing capacity of 96 kg [211.7 lb].
zThe fastening torque of the expansion bolt reaches 30 N•m [265.5 lbf•in.] the expansion bolt works properly,
and no damages such as cracks are on the wall.

zBefore connecting a power cable,
ensure that other end of the power cable
not connected to any power supply.
zUse the DC RRU power cable clip to
press the shielding layer tightly and
ensure that the lower part of the
shielding layer does not exceed the
position shown in the preceding figure.
zGround the shielding layer at the
other end of the power cable.
zDo not remove the dustproof cap from
the idle antenna port, and use the
waterproof tape to wrap the joint.
zFor details on how to add OT
terminals to the DC RRU power cable of
the RRU, see page 22 " Adding OT
Terminals by Using a Wire Stripper."
zWhen wrapping the waterproof tape,
apply even force to extend the tape until
the width of the tape is 1/2 of the
original width.
zWrap the joint spirally upward,
downward, and then upward again. In
other words, the joint is wrapped by
three layers of the tape. Ensure that the
two immediate layers overlap with each
other about half the width of the tape.
For details, see page 24 “Waterproofing
Outdoor Cables.”
zInstall the optical module before
installing the optical cables. For details,
see page 25 “Installing the Optical
Module.”
After the cables
are installed on

Adding the OT terminals to the power cable involves adding OT terminals to the RRU
power cable and adding OT terminals to the shielding layer of the RRU power cable.
bAdding OT Terminals by Using a Wire Stripper (Recommended)
Determine lengths of power cables for
different operations according to the scales on
the inner side of the cover plate of the cabling
cavity.
Based on the determined length, remove the
jacket and shielding layer off the power cable.
Add an OT terminal to each wire.
Strip a 15 mm jacket off the power cable to
reveal the shielding layer of the power cable
Remove the jacket from each wire.
The OT terminals must be added to the power cable before the RRU is installed on a metal pole.
