Procedure
Step 1 Determine the position for installing the pRRU based on the construction blueprint and the
clearance requirements.
Step 2 Place the mounting bracket in the installation position against the wall. Then, level the
mounting bracket and use a marker to mark four anchor points. See Figure 8-6.

Step 3 Use a hammer drill with φ6 bore to drill holes at the marked anchor points, as shown in
Figure 8-7. Use a vacuum cleaner to clean the dust inside and around the holes and measure
the distance between them. If they are inaccurately positioned, re-measure and re-drill the
holes. Then, use a rubber mallet to hit a plastic expansion sleeve into each hole.
