Metal pole	63								30
				Angle steel			U-steel

RRU

Angle steel or U-steel

The brackets cannot be combined when the RRUs are installed on the wall.

The angle between the vertical and the angle steel or U-

≤10° steel or angle steel where the RRU is installed must be less than or equal to 10 degree.

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.

Installing the RRU on a Metal Pole

aInstalling a Single RRU on a Metal Pole

1.Install the main bracket.

When installing the main bracket, ensure that the contact piece on the bracket is fixed.

1200 mm [47.2 in.]

1600 mm [63 in.]

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.

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.

40 N•m [354 lbf•in.]

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.

3. Install the RRU on the main bracket. When you hear click sound, you can infer that the RRU is in position.

z The weight-bearing capacity of the RF ports at the bottom of the RRU is low. Do not place the RRU at its bottom.

z During the operation, place the foam pad or cardboard under the RRU to prevent any damage to the housing of the RRU.

Installing the RRU on a Metal Pole

b Installing Two RRUs Back-To-Back on a Metal Pole

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.

3. Reinstall the attachment plate and cover plate on the second RRU by interchanging their positions.

4.8 N•m [42.5 lbf•in.]

4. Install the second RRU on the main bracket.

In reverse mode

In standard mode

Ensure that the cabling cavities of the two RRUs face the same direction when installing the RRUs.
