Important Notes
Please read before installing.
1. Caution: To avoid overheating and possible damage to other equipment, do not use to con-
trol receptacles, fluorescent lighting fixtures, motor-operated or transformer-supplied appli-
ances, or electronic low-voltage lighting fixtures.
2. Caution: Operating a dimmed magnetic low-voltage circuit with all lamps inoperative or
removed may result in current flow in excess of normal levels. To avoid possible transformer
overheating or failure, Lutron strongly recommends the following:
•Do not operate without operative lamps in place.
•Replace burned out lamps as soon as possible.
•To prevent premature failure due to overcurrent, use transformers with thermal protection
or fused primary transformer windings.
3. Install in accordance with all national and local electrical codes.
4. DO NOT use Maestro ® dimmers for compact Fluorescent (Energy Saver) lamps.
5. When no “grounding means” exist within the wallbox then the NEC
®
2005, 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 Satin ColorsTM series wallplates.
6. Do not paint Dimmers or Maestro Accessory Dimmers (MA-R, MSC-AD).
7. Maestro Dimmers are not compatible with standard 3-way/4-way switches, for use only
with Maestro Accessory Dimmers (MA-R, MSC-AD).
8. Maestro Accessory Dimmers (MA-R, MSC-AD) can not be used individually and must be
used in conjunction with a Maestro Dimmer in a 3-way/4-way application.
9. In any 3-way/4-way circuit use only one Dimmer with up to 9 Maestro Accessory Dimmers
(MA-R, MSC-AD).
10. Do not use where total lamp wattage is less than 40 W/VA or greater than wattage indicated
on unit label.
11. Operate between 0 °C (32 °F) and 40 °C (104 °F).
12. Smart Dimmers may feel warm to the touch during normal operation.
13. Recommended wallbox depth is 2.5" (64 mm) minimum.
14. Maximum wire length between the Dimmer and the last Maestro Accessory Dimmer (MA-R,
MSC-AD) is 250 feet (76 m).
15. Clean dimmers with a soft damp cloth only . Do not use any chemical cleaners.
16. DO NOT use Incandescent/Halogen or Electronic Low-Voltage dimmers
for Magnetic Low-Voltage lighting.
For Incandescent/Halogen Lighting use
an Incandescent/Halogen Dimmer.
MA-600, MSC-600, MSC-600M 600 W 120 V~ 60 Hz
MA-1000, MSC-1000, MSC-1000M 600 W 120 V~ 60 Hz 1000 W
For Magnetic Low-Voltage Lighting use

Purchase Separately.
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.

Important Wiring Information
When making wire connections, follow the recommended strip lengths and combinations for the
supplied wire connector. Note: All wire connectors provided are suitable for copper wire only.
For aluminum wire, consult an electrician.
Wire Connector:
Use to join one 14 AWG or 12 AWG
ground wire with one 18 AWG
dimmer ground wire.
Twist wire con-
nector tight.
Push-in Terminals: Insert wires fully.
NOTE: Push-in terminals are for use with
#14 AWG
solid copper wire only. DO NOT
use stranded or twisted wire.
Screw Terminals: Tighten securely.
Screw terminals are for use with #12 or
#14 AWG
solid copper wire only. DO NOT
use stranded or twisted wire.
Trim or strip wallbox wires to the length indicated by the strip gauge on
the back of the dimmer
OR
Wiring the Dimmer:
• Connect the green ground wire on the Dimmer to

Tap Button Options
• Tap once when unit is off -
Lights brighten smoothly to
preset intensity.
• Tap once when unit is on -
Lights dim smoothly to off.
• Tap twice quickly - Lights
brighten rapidly to full inten-
sity.
• Press and hold when unit
is on - Each time dimmer is
turned off delayed fade to
OFF can be activated. As the
tap button is held, the LEDs
will begin to flash. The first
flashing LED represents a 10
second fade to OFF. Each
additional flashing LED rep-
resents an additional 10
seconds of delay before
lights fade to OFF (up to 60
seconds of delay).

IMPORTANT NOTICE:
To replace bulb, power may be
conveniently removed by pulling
the
FASS switch out on both the
Dimmer and any Accessory
Dimmers.
For any procedure other than
routine bulb replacement, power
must be disconnected at the
main electrical panel.

Symptom
Light does not turn ON or no
LEDs turn ON.
Light turns ON and Dimmer
works, but Accessory Dimmer
does not work.
Light does not remain ON, LEDs
glow dimly or blink.
Tap switch on Accessory Dimmer
does not work at brightest level.
Possible Cause
•Front Accessible Service Switch (
FASS ) on Dimmer or
Accessory Dimmer is pulled out to the OFF position.
•Light bulb(s) burned out.
•Breaker is OFF or tripped.
•Wiring error. Call

*Note: The maximum lamp wattage is determined by the efficiency of the transformer,
with 70–85% as typical. For actual transformer efficiency, contact either the fixture or
transformer manufacturer. The total VA rating of the transformer(s) shall not exceed the
VA rating of the dimmer.
