Installing the BBU3900
a. Verify that the BBU3900 mounting ears are regularly
installed in a 19-inch rack, and are reversely installed
b. Install the BBU3900 in an
APM30H using a binding bracket.

screws when
installing the
RRU. Loosen
these screws
when removing
the RRU.

The angle between
the vertical and the
angle steel or Usteel or angle steel
where the RRU is
installed must be
less than or equal
to 10 degree.
z The RRU must be supported by foam or cardboard for protection.
z The RF ports at the bottom of the RRU cannot bear the weight of the RRU. Do not place the RRU on the
ground in the upright position.
Installing the RRU on a Pole

[Diameter: 60 mm (2 3/8'') to 114 mm (4 1/2'')]
1. Install the main bracket.
When installing the
main bracket,
ensure that the
contact piece on
the bracket is fixed.

The recommended diameter of the pole is 80 mm (3 1/8").
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
(354.03 lbf.in.). This secures the main and auxiliary brackets to the pole.
Tighten the two dual-nut bolt assemblies

alternatively. After the brackets are secured,
use a measuring tape to measure the spacing
between the main bracket and the auxiliary
bracket on two sides and confirm that the
spacing is the same.
3. Install the RRU on the main bracket. When you hear click sound, the RRU is
securely installed.
b
[Diameter: 60 mm (2 3/8'') to 114 mm (4 1/2'')]
1. Install the first RRU. 2. Install the second main bracket.
