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.
1. Install the main bracket.

3. Reinstall the attachment plate and cover plate on the second RRU by interchanging
their positions.
1. Install an RRU. For details, see page 7
Installing a Single RRU on a Metal Pole.2. Install the main fixture for another RRU.
Ensure that the cabling
cavities of the two RRUs
face the same direction
when installing the RRUs.

4. Install the second main fixture.3. Fit the tabs on the attachment plate of the
RRU into the anchor slots on the main fixture.
5. Fit the tabs on the attachment plate of
the second RRU into the anchor slots on
the second main fixture.
6. Install the third RRU.
