8. Install the Electrical Box (If required).

WARNING:  Improper installation may result in 

electrical shock or serious injury. 
All 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 (for example, a RACO 232, 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 at right). 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. 

WARNING:  May result in electrical 

shock or serious injury. For safety, 
complete 

all wiring of the electrical boxes 

and accessories 

after the plate is fully 

installed and secured.

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

electrical box opening.

9. Install the Screen.

a.  Following the guidelines given by the screen 

manufacturer, continue to install the screen 
mounting brackets and then hang the screen.

TIP:  Use S-hooks to hang the screen 

from the brackets. Bend the ends of the 
S-hooks so the screen does not fall when 
it is rolled up.

Use the smallest
notches when 
attaching the 
RACO box.
