contact the manufacturer. The total VA rating of the transformer(s) shall not
exceed the VA rating of the dimmer.
IMPORTANT
-
CAUTION: Use only with permanently installed fixtures with dimmable screw-in LED, and dimmable self-ballasted compact fluorescent, halogen, or incandescent lamps. Use only to control the primary side of permanently installed transformer-supplied low-voltage lighting, or in combination with incandescent lamps. To reduce the risk of overheating and possible damage to other equipment DO NOT use to control receptacles, fluorescent lighting fixtures, non-ballasted or externally ballasted compact fluorescent lamps, motor-operated appliances, or transformer-supplied appliances.
-
Neutral is required for all load types.
-
Install in accordance with all national and local electrical codes.
-
When no “grounding means” exist within the wall box, the NEC® 2011, Article 404.9 allows a dimmer without a grounding connection to be installed as a replacement, as long as plastic, noncombustible wallplate is used. For this type of installation, twist a wire connector onto the green ground wire or remove the green ground wire on the dimmer and use an ap pro pri ate wallplate such as Claro or Satin Colors series wallplates by Lutron.
-
Protect the dimmer from dust and dirt when painting or spackling the wall.
-
This dimmer is not compatible with standard 3-way or 4-way switches. Use only with Lutron companion dimmers listed above.
-
In any 3-way / 4-way circuit use only one dimmer with up to 4 companion dimmers.
-
The maximum wire length between the dimmer and the farthest companion dimmer is 150 ft (45 m).
-
Operate between 32 °F and 104 °F (0 °C and 40 °C).
-
It is normal for the dimmers to feel warm to the touch during operation.
-
Clean the dimmer with a soft damp cloth only. Do not use any chemical cleaners.
For more information, please see www.lutron.com/cleaning -
For indoor use only.
Determine wiring configuration
3A ** For lights controlled from one location:
Fully wrap the
wires around the screw and tighten (A), or strip insulated wires to 1/2 in
(13 mm) and insert them into the push-in terminals (B). Solid copper wire
only.
3B For lights controlled from two locations:
NOTE: Dimmer must be wired on the load side. Connect Neutral to the
dimmer. Up to four companion dimmers may be used. For additional wiring,
assistance go to
www.lutron.com/wiringwizard
NOTE: Only one dimmer can be used per circuit. NOTE: Dimmer MUST be on the load side.
For more
information please go to
www.lutron.com/wiringwizard
NOTE: DO NOT install a dimmer on the line side.
3C For
lights controlled from three or more locations:
NOTE: Dimmer must be wired on the load side. Connect Neutral to the dimmer. Up to four companion dimmers may be used.
For additional wiring, assistance go to www.lutron.com/wiringwizard
NOTE: Only one dimmer can be used per circuit.

For use in a RadioRA 3 system, please refer to the Getting Started Guide:
www.lutron.com/RA3support
For reliable performance in a system, Clear Connect-Type X devices must be
placed within 25 ft (7.6 m) of two additional compatible Clear Connect-Type X
devices.
Clear Connect-Type X devices include, for example, RadioRA 3 Sunnata dimmer,
switch, keypad, and RadioRA 3 wireless processor/gateway devices. Companion
devices are excluded from the list of compatible devices because they are not
Clear Connect-Type X devices. Companion devices have wired communication with
the main device. For more information please refer to the Wireless Setup
guide: www.lutron.com/RA3support Setup for
use WITH a system
Troubleshooting
| Symptom | Cause | Action |
