4. Opstelling

4.1 Meganiese installasie

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 Elektriese bedrading

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. Register or log in to your Smartlife account.
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. Bedryfsinstruksies

5.1 Handbediening

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.
• Set schedules or timers for automatic operation.
• Monitor real-time current, voltage, en kragverbruik.
• Adjust protection parameters (OVP, UVP, OCP).

5.3 Beskermingskenmerke

The TOB1S-63 provides the following adjustable protection features:

• Oor Voltage Beskerming (OVP): Adjustable range 250-300V. The breaker will trip if the voltage exceeds this set limit.
• Onder Voltage Beskerming (UVP): Adjustable range 150-200V. The breaker will trip if the voltage drops below this set limit.
• Oorstroombeskerming (OCP): Adjustable range 1-63A. The breaker will trip if the current exceeds this set limit.
• Kortsluitingbeskerming: 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. Onderhoud

The TOMZN TOB1S-63 circuit breaker requires minimal maintenance.

• Inspekteer die bedradingsverbindings gereeld om te verseker dat hulle styf en vry van korrosie bly.
• Hou die toestel skoon en vry van stof en puin. Gebruik 'n droë, sagte lap vir skoonmaak.
• Moenie vloeibare skoonmaakmiddels of oplosmiddels gebruik nie.
• Verseker behoorlike ventilasie rondom die toestel om oorverhitting te voorkom.

7. Probleemoplossing

• Toestel word nie aangeskakel nie:
  • Gaan die hoofkragtoevoer na.
  • Verify all input wiring connections are secure.
• Stroombreker skakel gereeld uit:
  • Check for over-current conditions on the load.
  • Verifieer voltage 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.
• WiFi-verbindingsprobleme:
  • 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.
