Ganging

Remove side sections if mounting 2 or more devices side by side. No derating is required when ganging this product.

Important Notes

1. Only use dimmer with permanently installed incandescent or dimmable LED fixtures. To avoid overheating and possible damage to other equipment, do not use to control receptacles, fluorescent lighting fixtures, low-voltage lighting fixtures, magnetic transformer loads, motor-driven appliances, or transformer-supplied appliances.
2. Use switch to control any permanently installed lighting or fan load. Switch is rated for fan and lighting loads up to 2.5 A.
3. Install in accordance with all national and local electrical codes.
4. When no “grounding means” exists in wallbox, the 2011 National Electrical CodeR (NECR) allows a control to be installed as a replacement if 1) a nonmetallic, noncombustible faceplate is used with non-metallic attachment screws or 2) the circuit is protected by a ground fault circuit interrupter (GFCI). When installing a control according to these methods, cap or remove green wire before screwing control into wallbox and use an appropriate faceplate such as Claro or Satin Colors series wallplates by Lutron.
5. For indoor use only between 32 °F and 104 °F (0 °C and 40 °C).
6. Clean dimmers with a soft damp cloth only. Do not use any chemical cleaners.
7. Install per Lutron’s torque guidelines at lutron.com/torque
