- Connect Input: Connect the Live (L) wire from your power source to the "Input L" terminal on the smart switch. Connect the Neutral (N) wire from your power source to the "Input N" terminal on the smart switch.
- Connect Output: Connect the Live (L) wire leading to your load to the "Output L" terminal on the smart switch. Connect the Neutral (N) wire leading to your load to the "Output N" terminal on the smart switch.
- Secure Connections: Ensure all wire connections are tight and secure.
- Restore Power: Once wiring is complete and verified, restore power at the circuit breaker.
