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.

4. Install the second RRU on 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.

1. Install the main fixture and the auxiliary fixture. For details, see page 7

Installing a Single RRU in Ordinary Mode.

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.
