Important Notes

Install in accordance with all national and local electrical codes.
When no “grounding means” exists in wallbox, the National Electrical Code (NEC®) allows a control to be installed as a replacement when a plastic faceplate with plastic fasteners is used, or the circuit is protected by a ground fault circuit interrupter (GFCI). Lutron wallplates meet this requirement. Cap or remove green wire before screwing control into wallbox.
Protect the control from dust and dirt when painting or spackling the wall.
Clean the companion device 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.
For any 3-way / 4-way circuit, use only one Maestro dimmer (MACL-153M) with up to 9 companion devices.
Maximum wire length between the main control and the farthest accessory switch is 150 ft (45 m).

Disconnect Power

WARNING: SHOCK HAZARD. May result in Serious Injury or Death. Turn off power at circuit breaker or fuse before installing.
