Important Notes
1. CAUTION: Use "AY-" or "TG-" models only with permanently-
installed 120V incandescent or halogen fixtures. To avoid
overheating and possible damage to other equipment, do not use
to control receptacles, fluorescent lighting fixtures, motor-driven
appliances, or transformer-supplied appliances. 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.
2. CAUTION: Operating a dimmed low-voltage circuit 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 dimmed low-voltage circuits without operative
lamps in place.
• Replace burned-out lamps immediately.
• Use transformers with thermal protection or fused primary
windings to prevent transformer failure due to excess current.
3. When no “ground means” exists within the wallbox, then NEC
380-9 exception to (b) allows a dimmer without a ground
connection, to be installed as a replacement. For this type of
installation cap or remove the green dimmer ground wire. A
dimmer installed under this exception (NEC 380-9 exception to
(b)) must be provided with a plastic, noncombustible, UL listed
wallplate.
4. Recommended minimum load is 40 watts.
5. Protect dimmer from dust and dirt when painting or spackling.
6. Dimmer and wallplate screws may feel warm to the touch during
normal operation.
7. Only one dimmer can be used in a 3-way circuit.
8. For new installations, install a test switch before installing the
dimmer.
9. Install in accordance with all national and local electrical codes.
Installation
For installations involving more than one control in a wallbox, refer to
Multi-Unit Installations before beginning.
Step 1 WARNING: Turn power OFF at circuit breaker or remove
fuse.
Step 2 Remove switch mounting screws. Pull switch from wall.
Step 3 Identify type of circuit.
Step 4 Disconnect switch wires.
Step 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 (see Step 4 and below).

Step 6 Wire the dimmer. in a SINGLE-POLE circuit
• Connect the green or bare copper
ground wire to the green ground
screw on the dimmer (see
Important Note 3).
• Connect one of the remaining wires
removed from the switch to the
different-colored screw (or backwire
hole) on the dimmer.
• Connect the remaining wire
removed from the switch to the
screw (or backwire hole) opposite
the different-colored screw on the
dimmer.
• Note: If you are replacing a single-
pole switch with a 3-Way dimmer
(AY-603P or AY-103P), the screw
on the same side as the different-
colored screw, is not used. Tighten
it securely.

in a 3-WAY circuit.
• Connect the green or bare copper
ground wire to the green ground
screw on the dimmer (see
Important Note 3).
• Connect the tagged wire removed
from the switch to the different-
colored (COMMON) screw (or
backwire hole) on the dimmer.
• Connect one of the remaining wires
removed from the switch to either of
the remaining screws (or backwire
holes) on the dimmer.
• Connect the last wire removed from
the switch to the remaining screw
(or backwire hole) on the dimmer.
Step 7 Mount and align dimmer. Replace wallplate.
Step 8 Turn power ON.
