6.2 Passos d'instal·lació
- Desconnecteu l'alimentació principal al disjuntor.
- Connect the Live (L) and Neutral (N) wires from your mains supply to the corresponding 'L' and 'N' input terminals on the SM309-S module.
- Connect the Live (L) and Neutral (N) wires of your dimmable light fixture to the 'L' and 'N' output terminals on the SM309-S module.
- If using an external push-button switch, connect the switch to the 'A1' and 'A2' terminals. This allows for local manual control.
- Securely place the module within a suitable electrical box or enclosure, ensuring proper ventilation and adherence to local electrical codes.
- Resta l'alimentació al disjuntor.
7. Configuració i emparellament
