Important Notes
1. CAUTION: To reduce the risk of
overheating and possible damage to
other equipment, do not use to control
receptacles, motor-operated appliances,
or transformer-supplied appliances.
2. These dimmers require a neutral
connection in the wallbox. If your
wallbox does not have a neutral, one
must be run. The dimmers will not
operate without one.
3. When no “grounding means” exist within
the wallbox then the NEC® 2002, 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 Lutron's Claro® or FassadaTM series
wallplates.
4. Use with Lutron Hi-lume® FDB or Eco-
10TM Electronic Fluorescent Dimming
Ballasts only. Do not use with any other
ballasts.
(blue) on dimmer. To determine total
load on the dimmer circuit, refer to
ballast label. Each ballast has an
associated input current. The total load
is found by adding up all the ballast
currents for all ballasts on the dimmer.
6. Use only the lamp types listed on the
label of the ballast. Compact fluorescent
lamps must have 4 pins for dimming.
7. AYF-103P, DVF-103P, and DVSCF103P operate at 120V only. AYF-103P277, DVF-103P-277, and DVSCF-103P277 operate at 277V only.
8. In multi-phase applications, use a
separate neutral for each dimmer circuit.
If further information is necessary,
contact the Lutron Hotline 1-800-523-
9466.
9. Do not use two dimmers in the same 3way circuit.
10. Wire dimmer in accordance with all
national and local electrical codes.
11. This dimmer is designed to operate in
temperatures between 0°C and 40°C
(32°F to 104°F).
12. The Diva® dimmer is compatible with
designer-style and Lutron screwless
Claro® wallplates. The Ariadni® dimmer
is compatible with standard wallplates
and Lutron FassadaTM wallplate.
Wallplates are not included.
13. The wire connectors provided are
suitable for copper wire only. They can
be used to join one No. 18, 16, 14, 12,
or 10 gauge wire with one or two No. 14
or 12 gauge wires.
Dimmers can be grouped together or with
standard switches under a common
wallplate. When ganging these dimmers,
remove the inner side sections. No capacity
derating is required for these dimmers.
Remove all inner side sections
(shaded) in any ganged installation.
Do not remove outer side sections.
Before Installation
CAUTION: Check new installations for short
circuits BEFORE installing the fluorescent
dimmer. Turn power OFF at circuit breaker
or fusebox. Connect a standard switch as
shown in the Test Switch Wiring Diagram.
Turn power ON. If lights do not come on, a
break in the wiring exists. If the breaker
trips, there is a short in the wiring. If
necessary, turn power OFF and correct any
wiring problems, recheck the circuit, then
proceed to Installation. Warranty is void if
dimmer is turned ON in a shorted circuit.

4A. Single-pole wiring
(See Single-Pole Wiring Diagram)
• Connect the bare or green ground wire
of the dimmer to the bare or green
ground wire in the wallbox.
• Using a wire connector provided, cap off
the violet wire. This wire is only used in
a 3-way installation.
• Connect the white dimmer wire to the
neutral wire in the wallbox.
• Connect the blue dimmer wire to the
120V or 277V supply (hot) wire.
• Connect the red dimmer wire to the wire
going to the black wire of the ballasts.
• Connect the yellow dimmer wire to the
wire going to the orange wire of the
ballasts.
4B. 3-way wiring
(See 3-Way Wiring Diagram)
• Connect the bare or green ground wire
of the dimmer to the bare or green
ground wire in the wallbox.
• Connect the white dimmer wire to the
neutral wire in the wallbox.
• Connect the blue dimmer wire to one of
the two wires coming from the other
switch location.
• Connect the violet dimmer wire to the
second wire coming from the other
switch location.
• Connect the red dimmer wire to the wire
going to the black wire of the ballasts.
• Connect the yellow dimmer wire to the
wire going to the orange wire of the
ballasts.
5. Mount and align dimmer. Do not pinch
wires.
3. Strip insulation or trim wires to expose
1/2" or 5/8" of wire:
1/2" for 10, 12, and 14 gauge.
5/8" for 16 and 18 gauge.
1/2"or 5/8"
6. Screw on faceplate.
7. Turn power ON.

Lamp Aging
Best dimming performance is
achieved after new lamps have been
aged (burned-in) by running at full
intensity for at least 100 hours.
Minimum Light Level
Adjustment
This unit is factory calibrated and
does not normally require low-end
light level adjustment. If lamps flicker
or drop out at the minimum dimming
level, there may be an installation
error or the low-end light level may
need to be reset. Continued use of
the system in this mode will cause
premature lamp failure. If this is
occurring, call the
Support Center
