U-steel RRU Angle steel or U-steel The angle between the vertical and the angle steel or Usteel or angle steel ≤10° 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-steel or an angle steel. 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.

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. 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. 40 N•m [354 lbf•in.] 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. M6X16 4.8 N•m [42.5 lbf•in.] 4.

Installing the RRU on an Angle Steel Plan view Angle steel z The procedure for installing the RRU on an angle steel is the same as that for installing the RRU on a metal pole. z It is recommended that only one RRU be installed on an angle steel. 11 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. ≥650 mm [25.6 in.] ≥650 mm [25.6 in.] 128 mm [5 in.] Level 126.5 mm [5 in.] 126.5 mm [5 in.] 1200 mm [47.2 in.] to 1600 mm [63.0 in.] RRU z It is recommended that the auxiliary bracket be 1,200 mm [47.2 in.] to 1,600 mm [63.0 in.] above the ground. z The 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. M10x65 bolt Spring washer 10 Plastic tube Ø14 Flat washer 10 Expansion tube 55 mm [2.2 in.] to 60mm [2.4 in.] 90° Do not hammer the bolt entirely into the wall. Instead, leave 20 mm to 30 mm of the bolt outside the wall. 20 mm [0.8 in.] to 30mm [1.2 in.] After the expansion bolt is removed, dispose of the plastic tube. When the RRU is installed on a wall, the requirements are as follows: z For one RRU, the wall has a weight-bearing capacity of 96 kg [211.7 lb]. z The 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. 12 Installing the RRU on a Wall 3.
