Electronic Low Voltage Dimmer
MAELV-600, MSCELV-600M
(600 W maximum, 5 W minimum) 120 V , 60 Hz
Smart Remote
MA-R, MSC-AD
(8.3 A maximum) 120 V , 60 Hz
Important Notes
1. Caution: To avoid overheating and possible damage to other equipment,
do not use to control receptacles, fluorescent lighting fixtures, motor-operated or transformer-supplied appliances.
2. Install in accordance with all national and local electrical codes.
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
® series wallplates.
4. Do not paint Dimmers or Smart Remotes (MA-R, MSC-AD).
5. Use to control the primary side of electronic transformer-supplied low-
voltage lighting, incandescent lamps, or a combination of the two.
6. Some fixture manufacturers do not recommend dimming their solid-state
transformers. To determine if a fixture can be dimmed, consult the fixture
manufacturer.
7. This product requires a neutral wire in the wallbox. If a neutral wire is not
present, contact a licensed electrician for installation.
8. This control is overload protected. If the rated wattage is exceeded,
power to the circuit will shut off until the control cools. It this occurs,
remove excess load from the circuit.
9. Maestro® Dimmers are not compatible with standard 3-way switches, for
use only with Smart Remotes (MA-R, MSC-AD).
10. Smart Remotes (MA-R, MSC-AD) can not be used individually but must
be used in conjunction with a Maestro
® Dimmer in a 3-way/4-way applica-
tion.
11. Only one Maestro® Dimmer can be used in a multi-location circuit with up
to nine Smart Remotes (MA-R, MSC-AD). The Smart Remotes (MA-R,
MSC-AD) must be wired on the line side of the Dimmer.
12. In multi-phase applications, use a separate neutral for each phase containing a dimmed circuit.
13. Operate between 0°C (32° F) and 40°C (104° F).
14. Dimmer may feel warm to the touch during normal operation.
15. Recommended wallbox depth is 2 1/2" (64 mm) minimum.
16. Maximum wire length between the Dimmer and the last Smart Remote
(MA-R, MSC-AD) is 300 feet (91 m).
17. Clean with a soft damp cloth only. Do not use any chemical cleaners.
Multigang Installations
When combining controls in the same wallbox, 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. Reduction of
Dimmer capacity is also required. Refer to chart below for maximum Dimmer
capacity.
Breaking Side
Sections
IMPORTANT NOTICE:
FASSTM - Front Accessible Service Switch - to replace
bulb, power may be conveniently removed by sliding
FASS switch to the left, on both the Dimmer and any
Smart Remotes.
For any procedure other than routine
lamp replacement, power must be disconnected at
the main electrical panel.

Tap Switch Options
• Tap once - Lights adjust
smoothly to level set by rocker.
•
Tap twice quickly - Lights adjust
rapidly to full.
•
Tap again - Lights adjust
smoothly to off.
• Fade to OFF - Press and hold to
activate delayed fade to OFF. As
tap switch is held the bottom
LED will begin to flash indicating
a 10 second fade to off. Each
subsequently flashing LED represents 10 seconds of delay
before dimmer fades to OFF (up
to 60 seconds).
• Locked-in Preset - Tap 4 times
quickly to set the current light
level as the “Locked-in”preset
(the LEDs will blink twice indicating the preset was locked). When
the dimmer is turned ON via this
button it will always go to this
“Locked-in” light level rather than
the previous light level.To unlock
the preset, tap the switch 4 times
quickly (the LEDs will blink three
times indicating the preset was
unlocked).

Symptom
Light does not turn on.
Lamps flicker with low-voltage loads.
LEDs do not turn OFF when
FASSTM switch on the dimmer is in the OFF position
(to the left).
Lights cycle OFF and ON.
Dimmer does not respond
properly to a Smart
Remote.
Possible Cause
• Front Accessible Service Switch (FASSTM) on the
Dimmer or Smart Remote is switched to the left
(See Step 5).
• Light bulb(s) burned out.
• Breaker is off or tripped.
• Dimmer not wired correctly.
• Neutral not wired to Dimmer (white wire).
• Wrong load type used. Verify that load is electronic
low-voltage.
• The yellow and black wires are reversed. See wiring
diagram in Step 5 for correct wiring.
• Overload protection circuit active – remove excess
load to correct.
• Smart Remote is not on the line side of the Dimmer.
