Step 5 — Run signal and control cables to the PVM 220.
Run the signal and control cables either into cable clamps or through
conduit attached to the PVM 220 enclosure (see figure 7).
To install a cable clamp on the enclosure:
a. Select a suitable sized cable clamp for the quantity and
thickness of cable to be fed into the enclosure. See the note
on page 3, Step 4 for knockout sizes.
b. Identify the most suitable cable entry point and remove one
or more knockouts as needed.
NOTE: Remove only the knockouts that are to be used
for cabling. Leave intact the unused knockouts.
c. Remove the large nut from the back of the cable clamp and
insert the clamp into the enclosure knockout from the inside.
d. Place the nut on the clamp and tighten to secure.
e. Pass the cables through the clamp into the enclosure. Leave
enough cable slack at the PVM 220 to ensure cable connection
to any device is maintained when the access door is open.
f. Tighten down the cable clamp until the cables are held firmly.
Avoid damaging or bending cables at too sharp an angle.
NOTE: See the PoleVault System Installation Guide for
full cable connection details.
Step 6 — Install devices onto the device mounting plate.
NOTE: The maximum door load is 15 lbs (6.8 kg).
To mount the devices and accessories:
a. Carefully align the switcher with the appropriate holes in the
marked location (indicated by arrows on the mounting plate).
b. Secure the switcher with the supplied #4-40 » inch mounting
screws, tightening each one until snug. Do not overtighten.
c. Mount the power supply onto the device mounting plate in the
marked location (indicated by arrows on the mounting plate), using
the supplied screws.
NOTE: Replacement power supplies must be either the
equivalent Extron power supply, or a UL Listed NEC
Class 2 power supply.
d. Mount any other devices following the procedures in the
supplied device guide.
Step 7 — Cut and install the ceiling tile in the access door.
NOTES:
• The door can accept a ceiling tile thicknesses of
Œ
-1… inches. Check the tile thickness before cutting.
• If the ceiling tiles have a specific pattern direction, ensure
the overall pattern direction is maintained when cutting
and fitting the cut tile insert into the access door.
a. Mark the dimensions (22 inches by 21.5 inches) for the PVM 220
access door on the installation tile and cut the tile to size.
b. With the access door open, insert the cut ceiling tile into the
door frame (see figure 10, on page 5).
