4. Configuració
4.1 Instal·lació mecànica
- Ensure all power is disconnected at the main breaker.
- Mount the TOB1S-63 circuit breaker onto a standard 35mm DIN rail by engaging the clips on the back of the device.
4.2 Cablejat elèctric
The TOB1S-63 is a 3P+N device. Connect the incoming power supply to the 'Power' terminals and the load to the 'Load' terminals as indicated on the device.
- Connect the three phase lines (L1, L2, L3) and the neutral line (N) to the respective 'Power' input terminals.
- Connect the corresponding load lines (L1, L2, L3, N) to the 'Load' output terminals.
- Ensure all screw-type terminals are tightened securely to prevent loose connections and arcing.

4.3 WiFi Network Connection (TUYA Smartlife App)
- Download the 'TUYA Smartlife' app from your smartphone's app store.
- Registra't o inicia la sessió al teu compte de Smartlife.
- Ensure the circuit breaker is powered ON. The 'Signal' indicator light should be blinking. If not, press and hold the 'Press 10s network' button until it blinks rapidly.
- In the Smartlife app, tap '+' to add a device. Select 'Electrical' > 'Circuit Breaker (Wi-Fi)'.
- Follow the on-screen instructions to connect the device to your 2.4GHz WiFi network.
- Once connected, the 'Signal' indicator will become solid.
4.4 RS485 Modbus Connection (Optional)
For RS485 Modbus communication, connect the A and B terminals of the circuit breaker to your Modbus network. Refer to the Modbus protocol documentation for specific register addresses and communication parameters.
5. Instruccions de funcionament
