3.4 Installation Scenarios
An RRU can be installed on a pole, U-steel, angle steel, wall, or IFS06. Installation scenarios must meet heat-dissipation and waterproofing requirements of the RRU.
Requirements for the Installation Scenarios
RRU is a professional communications equipment and cannot be installed in areas which are accessible to people. The installation scenarios involve the related security features. For details about specific requirements and precautions, see Safety Information.
Application scenarios: To ensure proper heat dissipation of the RRU, the following requirements must be met:
The RRU cannot be installed in an enclosed cabinet without a cooling system.
The RRU cannot be installed in an enclosed camouflage box.
The RRU cannot be installed in an enclosed equipment room without a cooling system.
When multiple RRUs are installed in centralized mode, the minimum clearance requirements must be met. For details about the minimum clearance requirements, see
3.5.2 Clearance for Three or More RRUs and 3.5.3 Installation Spacing Between RRUs.
If the RRU is inappropriately installed, heat dissipation of the RRU deteriorates and the RRU may not work properly, as shown in Figure 3-4.

Installation restrictions:
The specifications of installation supports described in this document are only based on the exterior and dimensions of the mounting kits. Before installing equipment, assess the strength and reliability of the installation support to determine whether it can bear the weight of the equipment.
If an AC RRU consists of a 18 L blade RRU and an OPM15M/OPM15M(Ver.B), this AC RRU cannot be installed in side-mounted mode.
To ensure the heat dissipation of the RRU and waterproofing of the ports at the bottom of the RRU, the vertical deviation angle of an RRU must be less than or equal to 10 degrees, as shown Figure 3-5.
On a tower, an RRU can be installed on a pole, angle steel, or U-steel. The side-mounted installation mode (one side instead of the rear of an RRU is mounted on the support) is recommended for RRUs on the main pole secured on a tower. This installation mode allows the RRU stacked installation. When the horizontal distance between the main and auxiliary poles on a tower is greater than or equal to 810 mm (23.62 in.), the side-mounted mode is recommended for installing RRUs on the auxiliary pole to meet the minimum clearance requirements. Otherwise, the standard mode is recommended for installing RRUs on the auxiliary pole.
RRU stacked installation is not allowed in indoor scenarios.
RRU stacked installation is allowed only when installed on one or more poles in outdoor scenarios, and a maximum of three RRUs can be stacked installation.

(1) RRU
(2) Installation support (pole, U-steel, angle steel, or wall)
When the operator faces the RRU whose handle and cabling cavity are on the right-hand side, the side facing the operator is the front of the RRU, and the other side is the back of the RRU.
Standard installation: RRU mounting kits are installed on the back of an RRU.
Reverse installation: RRU mounting kits are installed on the front of an RRU.
Side-mounted installation: RRU mounting kits are installed on the side face (not the side face of the maintenance cavity) of an RRU.
Stacked installation: Two or more RRUs are installed next to each other at the same level by stacking multiple RRU mounting kits.

The diameter of a pole for installing an RRU ranges from 60 mm (2.36 in.) to 114 mm (4.49 in.). The recommended diameter is 80 mm (3.15 in.).
The recommended thickness of the pole wall is 3.5 mm (0.14 in.) or above.
When RRUs are installed on a pole, the side-mounted installation is recommended. A maximum of three RRUs can be installed on a pole with the diameter ranging from 60 mm (2.36 in.) to 76 mm (2.99 in.).
Only a pole whose diameter ranges from 76 mm (2.99 in.) to 114 mm (4.49 in.) supports more than three RRUs.

Installing an RRU on a Wall
The wall for installing RRUs must meet the following requirements:
For each RRU, the wall must be able to bear a weight four times heavier than the RRU's weight and the bolts' pulling force of 1.25 kN (281.25 lbf) vertical to the wall.
Expansion bolts must be tightened to 30 N·m (265.52 lbf·in.) to ensure that the bolts work properly and the wall remains intact.

Installing an RRU on an IFS06
The upper and lower adjustable beams on an IFS06 can be moved up and down to fit for heights of RRUs.
The IFS06 supports at least three RRUs when the ambient temperature is higher than or equal to the lowest operating temperature of the RRUs and at least 5°C (41°F) lower than the highest operating temperature of the RRUs. The IFS06 supports a maximum of six RRUs when the ambient temperature is higher than or equal to the lowest operating temperature of the RRUs and at least 10°C (50°F) lower than the highest operating temperature of the RRUs.
For details about the operating temperature of the RRUs, see section "Technical Specifications of RRUs" in Base Station Technical Description.
RRUs cannot be stacked when the RRUs are installed on an IFS06, as shown in Figure 3-18.

If an RRU is installed on the bitumen ground, the RRU must be at least 500 mm (700 mm or more is recommended) away from the bitumen ground. The following describes the space requirements for installing a single RRU on the non-bitumen ground.
The recommended clearances ensure normal running and provide appropriate space for operation and maintenance (O&M). If the installation space is sufficient, leave the recommended clearances after installing the equipment.
The minimum clearance ensures normal running and heat dissipation, but O&M activities such as checking indicator status and opening the cabling cavity cannot be properly conducted. If the installation space is restricted, leave the minimum clearance after installing the equipment.
