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"

4.Wire the dimmers as shown in the following

diagrams:
To wire a single pole dimmer (C-600P, C-10P):

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 wires to the 2 wires removed
from the switch (see Figure A). The hot wire may be
connected to either of the dimmer wires. Be sure no
copper wire is exposed below the wire connectors.

Short Circuit Check: Check new installation for
short circuits prior to installation of dimmer by using a
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 Centurion 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.

To wire a 3-Way dimmer (C-603P, C-103P) :

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 black wire on the dimmer to the wire
removed from the odd color screw on the switch.

• Connect one of the red wires on the dimmer to one
of the remaining wires from the switch.

• Connect the other red wire on the dimmer to the
remaining wire from the switch. See Figure B.

inscription on knob indicates light level. When
dimmer is at the lowest light intensity, the knob
should be positioned as shown in Figure C. If not,
remove knob from the stem, align in the correct
position, and push securely back on.

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.

1. Determine the number of switchboxes necessary

by using the Switchbox Requirement Chart (Table A).
When ganging any combination of small controls
(C-600P, C-603P, C-10P, C-103P) and large controls,
place all small controls together at one end of the
gang and all large controls at the other end of the
gang.

*See item #2

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 E.

8.Snap faceplate on. See Figure D.

3. Turn power OFF. Wire each dimmer according

to step 4 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 F).
Allow 1/32" between controls for ease in attaching
faceplates.

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. Just snap on multiple single faceplates and

adjust up or down for snug fit.

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.

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 4 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. Just snap on multiple single faceplates and

adjust up or down for snug fit.

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 a few times. Hold faceplate steady as you
rub to keep a true edge.
