Binding the RRU and Installation Components

and through the handle, bind the main and auxiliary brackets with the lifting rope, and
then bind the steering rope with the handle of the RRU, as shown in the following
figures.

Do not bind the lifting rope
only on the handle when
lifting the RRU.
z
When lifting the RRU and installation components to the tower,
prevent the RRU from colliding with the tower.
z
The cross-sectional area of the lifting rope and steering rope is
around 20 mm, not more than 25 mm. In addition, the ropes can bear
the weight four times more than that of the RRU.
When the RRU is unpacked, it must be powered on
within 24 hours.
