4. Mount switch to switchbox using screws

provided. Switch must be mounted vertically.

See Figure D.

5. Replace faceplate. Press firmly at top, middle,

and bottom to snap tabs into place.

6. Turn on power.

Ganging

Nova switches can be ganged without breaking off

side sections. The Nova design also allows for

break-offs to conserve space. See Table A or B for

the number of switchboxes you need.

When ganging any combination of small and large

controls, place all small controls at one end of gang,

all large controls at other end.

*See note below

Note: When ganging an even number of small controls without

removing side sections, you need an additional switchbox 3/4"

from the other switchbox(es). Use a chase nipple as a spacer.

See Figure E.

Installation

Caution: Use ordinary switch to check new

installations for short circuits before installing Nova

switch. Do not install switch until you are sure no

short is present.

Multigang Installations: In multigang installations

several controls are grouped horizontally in one

ganging switchbox. Multigang faceplates are

available from Lutron to simplify and beautify these

installations. If you are planning a multigang

installation, read ganging information before

beginning installation.

Installation

1. Turn power OFF at circuit breaker or fusebox.

Wiring with power on may cause injury or

damage switch. Warranty void if switch is

miswired.

2. Remove faceplate. Pull at sides to snap it off.

3. Connect switchbox leads to switch. See Figure

A, B, or C for wiring diagram. Note: If a bare

copper or green ground wire is not in the wallbox,

contact a licensed electrician.

Cutting Plastic Faceplates

Some faceplates will need to be cut if removing side

sections of dimmers and not using a multigang

faceplate.

To cut faceplates:

1. Position faceplate face down on soft cloth.

2. Press firmly and score groove on back of

faceplate with razor-sharp knife. Use vertical

side of groove to keep knife on straight course

(see Figure H.)

3. Bend section back and forth several times to

break it off. Do not use pliers.

4. Smooth edges by placing fine-grained sandpaper

on flat surface and rubbing edge of faceplate

over it a few times. Hold faceplate steady as you

rub to keep edge true.
