8.3.6 Installing a pRRUon a Keel

This section describes how to install a pRRU3901 on a keel. If a suspended ceiling plate
cannot bear the pRRU, the pRRU can be installed on the keel on the ceiling. The standard
keel with a width less than 45 mm, instead of the non-standard keel, is recommended.
Context
Before installing the pRRU on a keel, ensure that the keel is strong enough to bear the pRRU.


The keel used on the ceiling is thin. During installation, fix the mounting kits onto the large
surface instead of the small surface of the keel to prevent distorting the keel.
Procedure
Step 1 Determine the position for installing the pRRU based on the construction blueprint and the
clearance requirements.

The mounting bracket of the pRRU can be installed on the keel of the following
specifications: GBT 11981-2008, JIS A6517-2002, and ASTM C635 C635M-2007. The
installation mode depends on onsite requirements because there are various keels.
This section describes the procedure of installing a pRRU on the keel of JIS standard
used in Japan. The procedure of installing a pRRU on other keels is the same as that of
installing a pRRU on the keel of JIS standard.
For details about the clearance requirements, see 8.1.3 Space Requirements.
