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.
