The minimum installation clearance meets the requirements of the equipment for normal running and heat dissipation, but does not meet the requirements for Operation and Maintenance (OM) such as checking the status of the LEDs and opening the maintenance cavity. When the installation space is restricted, the minimum installation clearance can be adopted.

The recommended installation clearance meets the requirements of the equipment for normal running and OM. When the installation space is sufficient, the recommended installation clearance can be adopted.

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

A maximum of two RRUs can be installed on a metal pole with a diameter of 60 mm to 75 mm, 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 to 114 mm in a centralized way.

It is recommended that only one RRU be installed on a U-steel or an angle steel.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.

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.

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

During 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. In this way, the main and auxiliary brackets are secured on the pole.

1. Install the main bracket.

Do not hammer the bolt entirely into the wall. Instead, leave 20 mm to 30 mm of the bolt outside the 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.

2. Drill holes at the anchor points and then install the expansion bolt assemblies.

It is recommended that the auxiliary bracket be 1,200 mm to 1,600 mm above the ground.

The RRUs cannot installed on a wall in centralized mode. Therefore, expansion bolt assemblies should be prepared for each RRU. 1200 mm～1600 mm

g Closing the Cover Plate of the RRU Cabling Cavity

Use the DC RRU power cable clip to press the shielding layer tightly and ensure that the lower part of the shielding layer does not exceed the position shown in the preceding figure.

Ground the shielding layer at the other end of the power cable.

Do not remove the dustproof cap from the idle antenna port, and use the waterproof tape to wrap the joint.

For details on how to add OT terminals to the DC RRU power cable of the RRU, see page 33 " Adding OT Terminals to the DC RRU power Cable of the RRU."

When wrapping the waterproof tape, apply even force to extend the tape until the width of the tape is 1/2 of the original width.

Wrap the joint spirally upward, downward, and then upward again. In other words, the joint is wrapped by three layers of the tape. Ensure that the two immediate layers overlap with each other about half the width of the tape. For details, see page 34 “Waterproofing Outdoor Cables.”

Install the optical module before installing the optical cables. For details, see page 34 “Installing the Optical Module.”

Powering On the RRU

The power switch must be set to OFF. Then, check the input voltage and ensure that the voltage ranges from -36 V DC to -57 V DC if -48 V DC power is supplied or 150 V AC to 300 V AC if AC power is supplied.

When the RRU is unpacked, it must be powered on within 24 hours.

1. Bind the RRU by leading the lifting rope along the lower part of the adapting piece and through the handle, bind the main and auxiliary brackets with the lifting rope, and then bind the steering rope with the handle of the RRU, as shown in the following figures.

2. Lift the RRU and installation components to the tower.

Do not bind the lifting rope only on the handle when lifting the RRU.

When lifting the RRU and installation components to the tower, prevent the RRU from colliding with the tower.

Lift the RRU to the tower before it is installed on the metal pole, angle steel, or U-steel.

Installer A climbs onto the tower. Then, installer A fixes the pulley to the support of the tower platform and leads the lifting rope through the pulley.

Installer C uses a lifting rope to bind the RRU and installation components as shown in the preceding figure and then ties a knot in the steering rope at the handle of the RRU.

Installer B pulls the lifting rope, and at the same time, installer C pulls the steering rope away from the tower to prevent the RRU and installation components from colliding with the tower.

Installer A holds the RRU and installation components and untie the ropes.

Waterproofing Outdoor Cablesd

The waterproof tape should be wrapped for an extra length of 20 mm away from the connectors at both ends.

The tapes should be wrapped around the connector from the lower part to the upper part. When wrapped for another layer, the tapes may not be cut.

When wrapping the waterproof tape, apply even force to extend the tape until the width of the tape is 1/2 of the original width.

When wrapping the waterproof tape, ensure that the upper layer of the tape covers at least 50% of the lower layer.

The insulating tape should be wrapped for an extra length of 20mm away from the connectors at both ends.

The last layer of the waterproof tape should be wrapped from the lower part to the upper part to prevent rainwater from infiltrating into the tape.
