8.3.5 Installing a pRRU on a Plate

This section describes how to install a pRRU on a plate. If a suspended ceiling plate has
adequate load bearing capacity and installation space, the pRRU can be installed on the plate.
However, it is good practice not to install a pRRU on an aluminum plate. The installation
modes are classified into installation on a removable suspended ceiling plate and installation
on an overall suspended ceiling.

Installation on a removable suspended ceiling plate
This installation mode applies when the suspended ceiling plate (for example, a metal
plate) is removable.
a. Determine the position for installing the pRRU based on the construction blueprint
and the clearance requirements.
For details about the clearance requirements, see 8.1.3 Space Requirements.
b. Place the mounting bracket in the installation position against the wall. Then, level
the mounting bracket and use a marker to mark two anchor points. See Figure 8-18.

To prevent inhalation or eye contact with dust, take adequate preventive measures when drilling holes.
Use a hammer drill with φ6 bore to drill holes at the anchor points.
c.
d. Lead two bolts (M4) through the mounting bracket and the suspended ceiling plate,
and use a torque screwdriver to torque the bolts to 1.4 N•m, as shown in Figure
