Installing an RRU on a Wall

The wall on which RRUs are installed must meet the following requirements:



When a single RRU is installed, the wall can bear at least four times the weight of the

RRU.



Expansion bolts must be tightened with a torque of 30 N·m (265.52 lbf·in.) to ensure the

bolts work properly and the wall remains intact without cracks in it.
