Multigang Installations: A multigang faceplate is

available to simplify and improve the appearance of
your installation. A multigang mounting frame is
provided with each standard multigang faceplate to
ensure proper alignment of the dimmers, easy
application of the faceplate, and a flat surface for the
installation. Refer to instruction sheet supplied with
multigang faceplates.

Single Unit Installation

1. Turn power OFF at fusebox or circuit breaker.

Wiring with power on can result in personal injury.
Damage to product caused by wiring with power on
voids warranty.

2. Remove faceplate from dimmer to prevent

damage and to access mounting holes. Pull out at
top and bottom edges, plate will snap off.

3.Strip insulation from dimmer wires and from wires

to which dimmer is to be connected as follows:

• 1/2" for 10, 12, and 14 gauge wire

• 5/8" for 16 and 18 gauge wire

1/2" or 5/8"

Lamp Type: Use this product with incandescent and

quartz lamps

only

--120VAC, 60Hz. Do

not

connect

to low-voltage lamps or any appliance.

Caution: To avoid overheating and possible
damage to other equipment, do not install to
control receptacles, fluorescent lighting fixtures,
motor-operated appliances, or transformer
supplied appliances.

Short Circuit Check: Check new installation for

short circuits prior to installation of dimmer by using a
single pole switch and connecting the appropriate
terminals to the hot wire and the lamp with power
OFF. Turn power on. If lights do not work, or
breaker trips, a short is present. Correct the wiring
and check circuit again. Install dimmer only when
short is no longer present.

Wire Connectors: Wire connectors provided can be
used to join one 10-, 12-, 14-, 16-, or 18-gauge wire
with one or two 12- or 14-gauge wires. Use them with
copper wire

only.

Switchbox and Location: A single-gang switchbox
(3" high x 2" wide x 21/2" deep) will service all
individual Nova dimmers. These dimmers are
designed to operate in ambient temperatures from
0oC to 40oC (32oF to 104oF). Allow a minimum space
of 41/2" above and below the dimmers for proper heat
dissipation.

• Using the wire connectors provided, connect the
green or bare ground wire on the dimmer (if
present) to the green or bare copper ground wire in
the wallbox. Note: If a green or bare copper ground
wire is not in the wallbox, contact a licensed
electrician.

• Connect the 2 dimmer leads to the 2 wallbox leads
(see Figure A). The hot wire may be connected to
either of the dimmer wires. Be sure copper
conductor is not exposed.

1. Determine the number of switchboxes necessary

by using the Switchbox Requirement Chart (Table A).
When ganging any combination of small dimmers
(N-600, N-1000) and large dimmers (N-1500, N-

2000), keep all small together at one end of the gang

and all large dimmers together at the other end of the
gang.

2. When ganging an even number of small controls

use gangable switchboxes with tapped ears. Do not
use plaster rings or gangbox covers. One switchbox
in addition to the total number of controls is required
in order to provide space for faceplates (e.g. 4
dimmers require 5 switchboxes). Place additional
switchboxes 3/4" apart from other switchbox(es) to
provide space for faceplate(s). See Figure D.

7.Turn power ON. Push slider up to increase light

and down to decrease light. Full "down" position will
turn light off.

Multigang Installation-

No Side Sections Removed (No Derating Required)

In multigang installations several dimers or controls
are grouped horizontally in one ganging switchbox or
in a series of connected switchboxes. Multigang
faceplates are available to simplify and improve the
appearance of this installation. A multigang mounting
frame is provided with standard multigang faceplates
which ensures proper alignment of dimmers, easy
application of the faceplate, and a flat surface for the
installation. Refer to instruction sheet (supplied with
multigang faceplate) when using these components.
Installation of dimmers without removing side
sections allows operation at full capacity (no
derating). Follow instructions below. For retrofit
installations side sections can be removed to fit
existing switchboxes. This requires derating and is
described in "Multigang Installation - Side Sections
Removed" on page 3.

to step 3 in "Single Unit Installation" on page 1.

4. Install controls in switchbox(es). Use center

mounting holes for first unit, then use offset mounting
holes as required for proper alignment (see Figure
E). Allow 1/32" between controls for ease in
attaching faceplates.

Multigang faceplates (with mounting frames and
instructions) are available in a variety of colors and
sizes to simplify and beautify your installation. See
Figure F.

2. Determine the number of switchboxes necessary

by using the Switchbox Requirement Chart (Table C).
When ganging any combination of small controls
(N-600, N-1000) and large dimmers (N-1500, N-

2000), place all small controls together at one end of
the gang and all large controls at the other end of the
gang.

Multigang Installation--

Side Sections Removed (Derating Required)

In multigang installations several dimers or controls
are grouped horizontally in one ganging switchbox or
in a series of connected switchboxes. Multigang
faceplates are available to simplify and improve the
appearance of this installation. A multigang mounting
frame is provided with standard multigang faceplates
which ensures proper alignment of dimmers, easy
application of the faceplate, and a flat surface for the
installation. Refer to instruction sheet (supplied with
multigang faceplate) when using these components.

1. Derating is necessary when side sections are

removed. Use Derating Chart (Table B) to determine
maximum wattage of lamps safely dimmed when side
sections are removed. Match the dimmer model
number and the number of side sections removed to
determine the maximum load that can be controlled.

3. Remove only inner side sections. Using pliers,

bend side sections as far as you can and then back
to their original positions. Repeat several times until
side sections break off (See Figure G).

Note:

Do not remove outer side sections of the two

dimmers which are on the ends of the gang.

5. Install controls in switchbox(es). Use center

mounting holes. (With large controls, you can use
offset mounting holes as required for proper
alignment). Allow 1/32" between controls for ease in
attaching faceplates.

6. Just snap on multigang faceplate (or multiple

single faceplates) and adjust up or down for snug fit.
Multigang faceplates (with mounting frames and
instructions) are available in a variety of colors and

Faceplate Cutting

Some faceplates will need to be cut if removing side
sections of dimmers and not using a multigang
faceplate. Position faceplate on a soft cloth face
down. Press firmly and score the groove on the back
of faceplate with a razor-sharp knife, using vertical
side groove to keep knife on straight course (see
Figure H). Bend section back and forth to break it off.
Smooth edges by placing fine-grained sandpaper on
a flat surface and rub edge of the faceplate over the
sandpaper an few times. Hold faceplate steady as
you rub to keep a true edge.

Figure H. Cutting Faceplate

Multigang faceplates, which eliminate the need to cut
individual faceplates, are available from Lutron in a
variety of colors to simplify and beautify your
installation.
