1. Turn off the power at the breaker or fuse box.
2. Identify and label the hot (live) and neutral (ground) wires.
3. Connect the hot wire to the switch’s “LINE” terminal.
4. Connect the ground wire to the switch’s “NEUTRAL” Terminal.
5. Check the wire: Make sure that multi-strand copper wire does not have loose strands, as they can cause a short circuit.
6. Secure the switch and switch plate.
7. Ensure there are no potential grounds nearby: Make sure you do not have a hand or any object that can act as a ground near the switch. Touch buttons can recalibrate themselves at startup, and any ground near the switch can affect this calibration.
8. Turn the power back on and test the switch.

Always prioritize safety, use the right tools, and consult an electrician if you’re uncertain about the process.
