Important Notes
Please read before installing.
1. CAUTION: Use “AY-” or “TG-” models only with permanently-installed
120 V incandescent or halogen fixtures. To avoid overheating and possible
damage to other equipment, do not use to con trol re cep ta cles, fluorescent
lighting fixtures, motor-driven appliances, or transformer-sup plied
appliances.
2. CAUTION: Use “AYLV-” models only with core and coil (magnetic) low-
voltage transformers. To control solid state (electronic) low-voltage
transformers, use Lutron® electronic low-voltage dimmers.
3. Operating magnetic low-voltage fixtures with all lamps inoperative or
removed may result in current flow in excess of normal levels. To avoid
possible transformer overheating and premature failure, Lutron strongly
recommends the following:
•Do not operate magnetic low-voltage fixtures without operative lamps in place.
•Replaceburned-outlampsimmediately.
•Usemagneticlow-voltagefixtureswiththermalprotectionorfusedprimary
windings to prevent transformer failure due to excess current.
4. When no “grounding means” exist within the wallbox then the NEC® 2008,
Article 404.9 allows a dimmer without a grounding connection to be installed
as a replacement, as long as a plastic, noncombustible wallplate is used. For
this type of installation, cap or remove the green ground wire on the dimmer
and use an appropriate wallplate such as Fassada® series wallplates by Lutron.
5. Recommended minimum load is 40 W.
6. Protect dimmer from dust and dirt when painting or spackling.
7. Dimmer may feel warm to the touch during normal operation.
8. Only one dimmer can be used in a 3-way circuit.
9. For new installations, install a test switch before installing the dimmer.
10. In stall in accordance with all national and local electrical codes.
11. Clean dimmer with a soft damp cloth only. Do not use any chemical cleaners.
12. Do not use with compact fluorescent lamps.
Align dimmer and
tighten screws
clockwise.
Turn screws clockwise
to start.
Push-In Terminal:
Insert screwdriver and pull wire out.
Or
Push-In Terminals: Insert wires fully.
Note: Backwire holes are for use with
14 AWG (1.5 mm
2
) solid copper wire only. For
aluminum wire, consult an electrician. DO NOT use
stranded or twisted wire.
Screw Terminals: Tighten securely. Screw terminals
are for use with solid copper wire only. For
aluminum wire, consult an electrician. DO NOT use
stranded or twisted wire.
Or
Turn screws
to loosen.

Multigang Installations
When installing more than one control in the same wallbox, it may be necessary to remove all inner side sections
prior to wiring (see below). Using pliers, bend side sections up and down until they break off. Repeat for each side
section to be removed. Removal of dimmer side sections reduces maximum load capacity. Refer to chart below
for maximum dimmer capacity.
Each control has inside
section removed.
Do not remove outer
side sections.
8 Turn power ON at circuit breaker (or replace fuse).

6 Wiring the Dimmer
Single-Pole Wiring
•Connectthebarecopperorgreen ground
wire to the green ground screw on the
dimmer (see Important Note 4).
•Connectoneoftheremainingwires
removed from the switch to the different-
colored screw (or backwire hole) on the
dimmer.
•Connecttheremainingwireremovedfrom
the switch to the screw (or backwire hole)
opposite the different-colored screw on
the dimmer.
5 Prepare Wires
Trim or strip wallbox wires to the length indicated by the strip gauge on the back
of the dimmer. Use the same procedure to wire your new dimmer as was used
with the old switch.
4 Disconnecting Switch Wires
2 Removing Wallplate and Switch
1 Turn power off at circuit breaker or remove fuse.
Important Note: Your wall switch may have two wires attached to the same screw
(see illustrations below for examples). Tape these two wires together before
disconnecting. When wiring, connect wires to dimmer the same way they were
connected to the switch.
Form wires carefully into the wallbox, mount and align dimmer.
Replace the wallplate.
One wire in the backwired
hole and one to the screw.
One continuous wire to
the screw.

switch with a 3-way or single-pole/3-way
dimmer, the screw on the same side as the
different-colored screw is not used. Tighten the
screw securely.
