5.4.6 pRRU Installed on a Keel
If the ceiling cover cannot bear the pRRU, the pRRU can be installed on the keel of a ceiling.
Context
Before installing the pRRU on a keel, ensure that the keel is strong enough to bear the pRRU.
l The installation kits 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
must depends on onsite requirements because there are various keels.
l 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.
Procedure
Step 1 Determine the position for installing the pRRU based on the construction blueprint and the space
requirements.
NOTE
For pRRU installation space requirements, see 5.1.3 Space Requirements.
Step 2 Lead the V clamp on across the keel, and mark the projective position on the cover with a marker,
as shown in Figure 5-22.
