Follow the wiring diagram carefully. If you are unsure about any steps, consult a qualified electrician.

1. Turn off power: Locate your circuit breaker and turn off the power to the switch you are replacing. Verify power is off using a voltage tester.
2. Remove old switch: Carefully remove the existing wall plate and switch from the electrical box.
3. Identify wires: Identify the Live (Line), Load, Neutral, and Ground wires. The Live wire typically carries power from the breaker, the Load wire goes to the light fixture, the Neutral wire completes the circuit, and the Ground wire provides safety.

   • Connect the Live wire (usually black) to the switch's Live (L-IN) terminal.
   • Connect the Load wire (usually red or black) to the switch's Load (OUT) terminal.
   • Connect the Neutral wire (usually white) to the switch's Neutral (N-IN) terminal.
   • Connect the Ground wire (usually green or bare copper) to the switch's Ground terminal.
5. Mount switch: Secure the smart switch into the electrical box with screws.
6. Install wall plate: Attach the 2-gang wall plate.
