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

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

z A 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.

z It is recommended that only one RRU be installed on a U-st eel or an angl e st eel . z When 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 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 th e RRU is low. Do not place the RRU at its bott om.

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

1. Install an RRU. For details, see page 7

Installing a Single RRU on a Metal Pole.

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

their positions.

2. Install the main fixture for another RRU.

4. Install the second RRU on the main bracket.

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