4. Opsætning

4.1 Mekanisk installation

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 Elektriske ledninger

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. Registrer dig eller log ind på din Smartlife-konto.
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. Følg instruktionerne på skærmen for at forbinde enheden til dit 2.4 GHz WiFi-netværk.
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. Betjeningsvejledning

5.1 Manuel betjening

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, og strømforbrug.
• Adjust protection parameters (OVP, UVP, OCP).

5.3 Beskyttelsesfunktioner

The TOB1S-63 provides the following adjustable protection features:

• Over Voltage-beskyttelse (OVP): Adjustable range 250-300V. The breaker will trip if the voltage exceeds this set limit.
• Under bindtage-beskyttelse (UVP): Adjustable range 150-200V. The breaker will trip if the voltage drops below this set limit.
• Overstrømsbeskyttelse (OCP): Adjustable range 1-63A. The breaker will trip if the current exceeds this set limit.
• Kortslutningsbeskyttelse: 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. Vedligeholdelse

The TOMZN TOB1S-63 circuit breaker requires minimal maintenance.

• Kontrollér ledningsforbindelserne med jævne mellemrum for at sikre, at de forbliver tætte og fri for korrosion.
• Hold enheden ren og fri for støv og snavs. Brug en tør, blød klud til rengøring.
• Brug ikke flydende rengøringsmidler eller opløsningsmidler.
• Sørg for korrekt ventilation omkring enheden for at forhindre overophedning.

7. Fejlfinding

• Enheden tænder ikke:
  • Kontroller hovedstrømforsyningen.
  • Verify all input wiring connections are secure.
• Circuit breaker trips frequently:
  • Check for over-current conditions on the load.
  • Bekræft bindtage 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.
• Problemer med WiFi-forbindelse:
  • 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.
