4. Impostazione

4.1 Installazione meccanica

1. Ensure all power is disconnected at the main breaker.
2. Mount the TOB1S-63 circuit breaker onto a standard 35mm DIN rail by engaging the clips on the back of the device.

4.2 Cablaggio elettrico

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)

1. Download the 'TUYA Smartlife' app from your smartphone's app store.
2. Registrati o accedi al tuo account Smartlife.
3. 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.
4. In the Smartlife app, tap '+' to add a device. Select 'Electrical' > 'Circuit Breaker (Wi-Fi)'.
5. Follow the on-screen instructions to connect the device to your 2.4GHz WiFi network.
6. 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. Istruzioni per l'uso

5.1 Funzionamento manuale

To manually turn the circuit breaker ON or OFF, use the red toggle switches on the front panel. Push up for ON, push down for OFF.

5.2 Smartlife App Operation

Once connected to the Smartlife app, you can:

• Remotely turn the circuit breaker ON/OFF.
• Impostare programmi o timer per il funzionamento automatico.
• Monitor real-time current, voltagee il consumo energetico.
• Adjust protection parameters (OVP, UVP, OCP).

5.3 Funzionalità di protezione

The TOB1S-63 provides the following adjustable protection features:

• oltre il volumetage Protezione (OVP): Adjustable range 250-300V. The breaker will trip if the voltage exceeds this set limit.
• Sotto il volumetageProtezione (UVP): Adjustable range 150-200V. The breaker will trip if the voltage drops below this set limit.
• Protezione da sovracorrente (OCP): Adjustable range 1-63A. The breaker will trip if the current exceeds this set limit.
• Protezione da cortocircuito: Non-adjustable, inherent protection against short circuits.

Adjust these settings via the Smartlife app interface for the device. After a trip event, investigate the cause before manually resetting the breaker.

6. Manutenzione

The TOMZN TOB1S-63 circuit breaker requires minimal maintenance.

• Ispezionare periodicamente i collegamenti dei cavi per assicurarsi che siano sempre ben saldi e privi di corrosione.
• Mantenere il dispositivo pulito e privo di polvere e detriti. Utilizzare un panno asciutto e morbido per la pulizia.
• Non utilizzare detergenti liquidi o solventi.
• Garantire un'adeguata ventilazione attorno al dispositivo per evitare il surriscaldamento.

7. Risoluzione Dei Problemi

• Il dispositivo non si accende:
  • Controllare l'alimentazione principale.
  • Verificare che tutti i collegamenti dei cavi di ingresso siano sicuri.
• L'interruttore automatico scatta frequentemente:
  • Check for over-current conditions on the load.
  • Verifica volumetage levels are within the set OVP/UVP ranges.
  • Inspect for short circuits in the connected load.
  • Adjust OVP/UVP/OCP settings if necessary, ensuring they are appropriate for your application.
• Problemi di connessione WiFi:
  • Ensure your router is 2.4GHz compatible.
  • Check WiFi signal strength at the device location.
  • Restart the circuit breaker and your WiFi router.
  • Re-attempt the pairing process in the Smartlife app.
• RS485 Modbus communication failure:
  • Verify A and B terminal connections.
  • Check Modbus network configuration and device address.
