f. Loop the safety cable through the center anchor or lag eye bolt,
attach it to the plate center holes (figure 6) and secure it with the
cable clamps.
g. Cut appropriate lengths of the supplied tie wire.
Loop the wire through the anchors or lag eye bolts and the
turnbuckles, then twist the wire around itself at least five times.
h. Tighten the turnbuckles by hand (see figure 6), and level the plate
so that it just rests on the grid.
ATTENTION: Potential Damage to Property.
• The four hanging wires should be taut, taking
the full weight of the completed installation.
• Overtightening the turnbuckles could cause
the T-bar assembly to be lifted, making the
suspended ceiling bowed and unsafe.
j. Tighten the four T-frame securing screws on the PCM.
Step 4 — Final Installation.
The PCM 240 comes with a threaded pipe adapter installed in the adapter
plate. This allows for an Extron PMP projector mounting pole to be fitted.
To fit the mounting pole, do the following:
a. Back out the set screws on the pipe adapter/adapter plate assembly.
b. Screw the pole into the adapter. A minimum of three full turns is
required to safely secure the pole in place
c. Secure the pole in place by tightening down the set screw on the
pipe adapter/adapter plate assembly. Cabling for the projector can
be accessed through the cut-out in the PMP pole.
d. Other optional accessories can also be installed at this point. These
include the Extron PMK 350, a low profile, two product mounting
kit, and the UPB 25, a Universal Projector Mounting Bracket suitable
for most projectors weighing up to 25 pounds.
e. Complete any further device installation according to the relevant
device manual.
