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.

Figure 3-4 Inappropriately installed RRU
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 anAC RRU consists of an 18 L blade RRU and an 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.
