LUTRON ST-RD Sunnata Companion Device Installation Guide

LUTRON ST-RD Sunnata Companion Device

Please read before installing

Important Notes

1. Install in accordance with all national and local electrical codes.
2. 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.
3. Protect the control from dust and dirt when painting or spackling the wall.
4. Clean the dimmer with a soft damp cloth only. Do not use any chemical cleaners.
5. For indoor use only.
6. In any 3-way/4-way circuit, use only one main control with up to 4 companions.
7. Maximum wire length between the main control and the farthest companion is 150 ft (45 m).
