Installing the DC RRU3908
e
Installing the RRU on a Metal Pole
3. Use an adjustable wrench to tighten the nut until the fastening torque is
40 N•m. In this way, the main and auxiliary fixtures are secured on the pole.
4. Install the RRU on the main bracket. When you hear a click, you can
infer that the RRU is in position.
The RF port at the bottom of the RRU does not have load bearing capacity. Do not place the
RRU on the ground on its bottom 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 screw is a non-fixed one and
can be neglected during the
installation.
It is only used when the RRU is
removed.
