Important Notes
Please Read Before Installation
Install in accordance with national and local electrical
codes.
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.

4.Push wires into switchbox, allowing room for
dimmer backbox to be inserted.
1/2" or 5/8"
Switchbox and Location: A single-gang switchbox
(3" high x 2" wide x 21/2" deep) will service all
individual Centurion dimmers. These dimmers are
designed to operate in ambient temperatures from
0°C to 40°C (32°F to 104°F). Allow a minimum
space of 41/2" above and below the dimmers for
proper heat dissipation.
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
• 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.

5.Mount dimmer to switchbox using 2 screws
provided and center mounting holes. Unit must be
mounted vertically. See Figure B.
6.Check knob for correct positioning. Lutron
inscription on knob indicates light level. When
dimmer is off, knob is positioned as shown in Figure
B. If not, remove knob from the stem, align in the
correct position, and push securely back on.
7.Snap faceplate on. See Figure C.
8.Turn power ON. Turn knob clockwise to increase
light intensity; counterclockwise to decrease light
intensity and click off.

1. Determine the number of switchboxes necessary
by using the Switchbox Requirement Chart (Table A).
When ganging any combination of small dimmers
(C-600, C-1000) and large dimmers (C-1500, C-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 to
provide space for faceplate(s). See Figure D.
3. Turn power OFF. Wire each dimmer according
to step 3 in "Single Unit Installation" on page 1.
4. Install controls in switchbox. 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 Installation-
No Side Sections Removed (No Derating Required)
In multigang installations several dimmers or controls
are grouped horizontally in one ganging switchbox or
in a series of connected switchboxes. 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.

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 F).
Note: Do not remove outer side sections of the two
dimmers which are on the ends of the gang.

Multigang Installation--
Side Sections Removed (Derating Required)
In multigang installations several dimmers or controls
are grouped horizontally in one ganging switchbox or
in a series of connected switchboxes.
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.
2. Determine the number of switchboxes necessary
by using the Switchbox Requirement Chart (Table C).
When ganging any combination of small controls
(C-600, C-1000) and large dimmers (C-1500, C-2000),
place all small controls together at one end of the
gang and all large controls at the other end of the
gang.
4. Turn power OFF. Wire each dimmer according
to step 3 in "Single Unit Installation" on page 1.
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. Remove appropriate sides of faceplates to match
the side sections removed from the controls (see
Faceplate Cutting). Then snap multiple single
faceplates onto controls and adjust up or down for a
snug fit.

Faceplate Cutting
Some faceplates will need to be cut if removing side
sections of dimmers. 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 G). 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 a few times. Hold
faceplate steady as you rub to keep a true edge.
