f.Using these dimensions, mark and cut a hole (using a 2 inch hole saw) for the projector pipe in the removed ceiling tile (see figure 3).

g.If required, to prepare the ceiling tile for a power outlet, use the PCM plate to trace and cut out the 2-gang hole in the ceiling tile for a

UL approved RACO® junction box.

If this is not required, proceed to step 3.

Step 2 — Install the Electrical Box.

The following method is recommended for integrating a RACO electrical box (not supplied) on the PCM base plate. A RACO box (#8471), an MK box, or standard UL electrical boxes can be inserted. Mounting holes for Extron

3 inch deep, ¼ rack wide devices are also included. Install the RACO box on the PCM plate as follows:

a.Attach the box to the plate, using the smallest notches in opposite corners of the cut-out. Do not tighten the screws fully at this time.

b.On the room side of the tile, slide the plaster ring under the screws.

c.Fully tighten the screws

WARNING: Risk of Personal Injury. For safety, complete all wiring of the electrical boxes and accessories after the plate is installed and secure.

All electrical installation should be done by a qualified electrician.

Step 3 — Secure the PCM Base Plate to the Ceiling.

Tie wire installation

a.Replace the cut ceiling tile, checking the orientation.

b.Replace the PCM base plate over the ceiling tile and align the hole with the PCM adapter plate.

c.Attach the four turnbuckles to the mounting plate, one at each corner.

ATTENTION: Risk of Personal Injury and property damage.

•DO NOT rest or lean on the mounting plate or suspended ceiling when attaching the turnbuckles and tie wire, or when drilling into the ceiling.

•For safest installation, insert the turnbuckle from the outside so that it hooks inwards.

d.Mark and drill four holes, approximately 1¼ inch (32 mm) deep into the ceiling joists, using a 1/4 inch (6.4 mm) diameter drill bit. Do this at 10 degrees out from vertical. Drill a fifth hole centered above the PCM for the safety cable (see figure 5). Minimum suitable joist size should be

2 inches by 4 inches.

e.Install appropriate anchors or lag eye bolts for the structural ceiling into each drilled hole.

Attach turnbuckles to long sides.
