8. Install the electrical box (if required)

WAll electrical installation should be performed by qualified personnel in accordance with local and national building codes, fire and safety codes, and local and national electrical codes.

If required, the following method is recommended for integrating a 4S Raco electrical box (not supplied) on the PCM base plate (e.g., a Raco 231, 2 1/8 inch deep, 4x4 inch electrical box and a Raco 778, 1/2 inch raised, 4x4 inch

plaster ring or similar).

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 (see figure 8a). Do not tighten the screws fully at this time.

b. On the opposite side of the PCM plate, slide the plaster ring under the screws. The plaster ring anchors the box in place with PCM plate sandwiched between.

c. Fully tighten the screws.

WFor safety, complete all wiring of the electrical boxes and accessories after the plate is fully installed and secure.

d. Mark and cut a hole in the ceiling tile for the electrical box opening.
