WARNING: Failure to provide adequate structural strength
for this component can result in serious personal injury or
damage to equipment! It is the installer’s responsibility to
make sure the structure to which this component is attached
can support five times the combined weight of all equipment.
Reinforce the structure as required before installing the
component.
1. Mark the six mounting hole locations through the ceiling
plate. (See Figure 1)
2. Drill six 7/32" holes.
3. Use six fasteners (not provided) to mount the ceiling plate
to the appropriate structural ceiling. The 1-1/2" NPT pipe
must be pointing down. (See Figure 1)
Figure 1
4. Thread the 1-1/2" NPT pipe (C) into the ceiling plate and
tighten securely.
WARNING: Installations using a column longer than 24
inches require the use of a CMA340 Support Cable
accessory.
5. Secure NPT pipe to ceiling plate using one 5/16-18x3/8" set
screw (I).
6. Attach RPA to projector arm (A) using four 1/4-20 X 1-1/2"
carriage bolts (H), four 1/4-20 acorn nuts (G) and 1/4" flat
