INSTALLATION INSTRUCTIONS
Single-Pole Wiring Application:
DI-000-ACM10-00A-X0
Tools needed to install your Dimmer:
Slotted/Phillips Screwdriver Electrical Tape
Pliers Pencil
Cutters Ruler
Installing Dimmer by itself or with other devices:
If installing Dimmer in a single device application, proceed with the
INSTALLING YOUR DIMMER section. If installing Dimmer in a
multi-device application, proceed as follows:
MULTI-DEVICE APPLICATION
In multi-dimmer installations, the reduction of the dimmer’s capacity
is required. Breaking off fins is not required on this device. Refer to
the chart for maximum load per dimmer.
MAXIMUM BULB WATTAGE
Low-voltage dimmers are rated in Volt-Amps (VA). The maximum
bulb wattage is determined by the efficiency of the transformer in
the low-voltage lighting system. Transformer efficiencies will vary
from different manufacturers; consider 80% efficient as average.
Use the chart to determine maximum bulb wattage for typical
transformer efficiency ratings.
INSTALLING YOUR DIMMER
NOTE: Use check boxes when Steps are completed.
WARNING: TO AVOID FIRE, SHOCK, OR DEATH;
TURN OFF POWER at circuit breaker or fuse and test
that power is off before wiring!

Step 3
Identifying your wiring application (most
common):
NOTE: If the wiring in the wall box does not resemble any
of these configurations, consult a qualified electrician.
WIRING DIMMER:
Connect wires per WIRING DIAGRAM as follows:
WARNING: FOR MAGNETIC LOW-VOLTAGE APPLICATIONS,
CONNECT DIMMER ONLY TO THE PRIMARY (HIGH-VOLTAGE)
SIDE OF A MAGNETIC LOW-VOLTAGE TRANSFORMER.
• Green or bare copper wire in wall box to Green dimmer lead.
• Line Hot wall box wire to Black dimmer lead.
• Load wall box wire to Red dimmer lead.
• Yellow/Red dimmer lead should have Red insulation label affixed.
NOTE: If insulating label is not affixed to Yellow/Red dimmer
lead, use electrical tape to cover.
• Proceed to Step 6.

• Pull off pre-cut insulation from dimmer leads.
• Make sure that the ends of the wires from the wall box are
straight (cut if necessary).
• Remove insulation from each wire in the wall box as shown.
WARNINGS AND CAUTIONS:
• To be installed and/or used in accordance with appropriate electrical codes and regulations.
• If you are unsure about any part of these instructions, consult a qualified electrician.
• To avoid overheating and possible damage to this device and other equipment, do not install to control a receptacle, fluorescent lighting, a motor- or a transformer-
operated appliance.
• Use with incandescent, 120V halogen fixtures or magnetic low-voltage transformers only. Use a Leviton electronic low-voltage dimmer to control electronic
(solid state) low-voltage transformers.
• When magnetic low-voltage circuits are operated at a dim level, with all lamps inoperative, excess current may flow through the transformer. To avoid possible
transformer failure due to overcurrent, use a transformer that incorporates thermal protection or a fuse at the primary windings.
• Acenti™ dimmers are not compatible with standard 3-way or 4-way switches. They must be used with compatible Acenti™ remotes for multi-location dimming.
WARNINGS AND CAUTIONS:
• Use only one (1) dimmer in a multi-location circuit with up to 9 coordinating remotes without LEDs or up to 4 matching remotes with LEDs. The remote(s) will turn the
light on at the brightness level selected at the dimmer.
• Total minimum load must exceed 40W.
• Dimmer may feel warm to the touch during normal operation.
• Recommended minimum wall box depth is 2-1/2".
• Maximum wire length from dimmer to all installed remotes cannot exceed 300 ft.
• Disconnect power at circuit breaker or fuse when servicing, installing or removing fixture.
• Use this device only with copper or copper clad wire. With aluminum wire use only devices marked CO/ALR or CU/AL.

IMPORTANT:
For 3-Way applications, note that one of the screw
terminals from the old switch being removed will usually be a different
color (Black) or labeled Common. Tag that wire with electrical tape
and identify as the common (Line or Load) in both the dimmer wall
box and remote wall box.

Installing your Alignment Plate:
Important Notice for Installer
To achieve proper aesthetic installation of the Acenti products, the
wall surface surrounding the wall box opening must be fairly flat
and free of irregularities. The wall box must be level and recessed
or flush to the wall surface. The Acenti installation system allows
for adjustments that will correct minor flaws that may be present in
the installation area.
This device must be installed with the Acenti™ Alignment Plate.
The Alignment Plate is packaged with the Acenti™ Wallplate,
which is sold separately from this device.
The Alignment Plate will function properly only if it is mounted to a
flat wall surface as described above.
• Leviton recommends to temporarily position the Alignment
Plate prior to wiring the device. If the wall box wires extend at
least 6 inches out of the wall box, it is also possible to install
the Alignment Plate after the device has been wired (refer to
Wallplate instruction sheet).
• The Alignment Plate must be installed with the tab towards the
bottom.
• Leviton recommends the following 3 methods to
temporarily
hold the Alignment Plate – use of device mounting screw, use
of wall box wires, or use of electrical tape (refer to the
following figures):
• For Single-Pole Application, go to Step 5a.
• For 3-Way Coordinating Remote (no LEDs) Application, go to
Step 5b.
• For 3-Way Matching Remote (with LEDs) Application, go to
Step 5c.
