Installation Instructions
WARNING: To avoid fire, shock, or death, turn off power at circuit breaker and test that power is off before wiring.
Lead Wire Identification:
- Black: Line/Hot
- White: Neutral
- Red: Load
- Green: Ground
- Remove wall plate and disconnect light switch. Make sure both "hot" and neutral wires are present in the junction box. (See Fig. 1). If both wires are not present, additional wiring may be necessary before installation can be completed.
- Connect red timer wire to wire from fixture using wire connector. Connect black timer wire to the "hot" (usually black or red) wire in junction box using wire connector. Cut white wire in junction box (or green splice) and strip 3/8" of insulation on both wires. Connect white timer wire to white wire in junction box using wire connector. (See Fig. 2).
- If the wall switch you are replacing had separate grounding conductors connected to the GREEN screw on the switch, make sure to connect these to the green wire from the timer with a wire connector.
- Check that all wire connections are secure.
- Place all wires inside junction box. Fit timer into junction box. Next, install timer using (2) mounting screws furnished.
- Reconnect your electrical power.
