5. Installation
The TONGOU Wi-Fi Smart Switch is designed for DIN rail mounting. Follow these steps for proper installation:
- Coupure de courant : Avant d'entreprendre tout travail électrique, assurez-vous que l'alimentation principale du circuit est coupée au niveau du disjoncteur.
- Montage: Mount the smart switch onto a standard 35mm DIN rail. The device occupies one position (18mm width).
- Câblage : Connect the power input (N for Neutral, L for Live) to the top terminals labeled 'Power'. Connect the load output (N for Neutral, L for Live) to the bottom terminals labeled 'Load'. The maximum wiring capacity is 10 mm² for both power and load sides. Ensure correct polarity.
- Protection du circuit: It is recommended to install an upstream residual current circuit breaker (RCBO/A type, 30mA/10kA) to protect the circuit.
- Connexions sécurisées : Use a screwdriver to securely tighten all wire connections.
