Secure The Projector Drop Ceiling Mount To The Ceiling - Extron electronics PVS 405D Installation Manual

7. Secure the Projector Drop Ceiling Mount
to the Ceiling.
a. Attach the four turnbuckles to the base plate,
one at each corner.
WARNING: May result in serious injury.
DO NOT rest or lean on the mounting
plate or suspended ceiling when attaching
turnbuckles, tie wire, or when drilling into
the ceiling.
NOTE: For safest installation, insert the
turnbuckle from the outside so that it
hooks inwards
b. Cut four equal lengths of the supplied hanging
wire, and loop the wire through the anchors or
lag eye bolts, and the turnbuckles, then twist
the wire around itself at least five times tightly at
each end.
c. Hand tighten the turnbuckles and level the plate
so it just rests on the T-frame.
CAUTIONS:
The four hanging wires should be taut,
•
taking the full weight of the completed
installation.
Do not overtighten the turnbuckles
•
or the T-frame assembly could be lifted,
making the suspended ceiling bowed
and unsafe
e. Pass the braided safety cable through the fifth
and center anchor and attach it to the center
holes on either side of the plate. Ensure the
cable is of equal length on both sides of the
anchor and secure the cable using the cable
clamps.
