Installing an RRU on a Wall
The wall for installing RRUs must meet the following requirements:
• For each RRU, the wall must be able to bear a weight four times heavier than the RRU's weight
and the bolts' pulling force of 1.25 kN (281.25 lbf) vertical to the wall.
• Expansion bolts must be tightened to 30 N·m (265.52 lbf·in.) to ensure that the bolts work
properly and the wall remains intact.
NOTICE:
• The standard installation is recommended for RRUs installed on a wall.
• When RRUs are installed on a wall in side-mounted mode, RRU stacked installation is not
allowed, as shown in Figure 13.
