5. Informació de seguretat

WARNING: Electrical installation should only be performed by qualified personnel. Ensure power is disconnected before installation or maintenance.

Important Note on Leakage Protection: If the protector trips three times consecutively due to leakage protection, the device will no longer automatically reconnect. This safety feature requires manual intervention. The user must check for the cause of the power failure and fix it to ensure personal safety before manually resetting the device. This prevents repeated exposure to potentially hazardous leakage conditions.

Use the 'set up', 'raise', and 'down' buttons on the device to navigate and adjust settings, or use the dedicated settings section within the Smart Life app.

7. Funcionament

7.1 Control manual

The device features 'ON' and 'OFF' buttons for manual control of the circuit. Press 'ON' to close the circuit and 'OFF' to open it.

7.2 Control remot mitjançant l'aplicació

Once paired with the Tuya Smart Life app, you can remotely monitor and control the circuit breaker:

• Encendre/apagar: Toggle the circuit breaker's status from your phone.
• Monitor Data: View vol en temps realtage, current, and accumulated kWh readings.
• Ajustar la configuració: Modify protection parameters and schedules.
• View Operation Records: Access historical data and event logs.

7.3 Control de veu

Integrate the Tuya Smart Life app with compatible voice assistants (e.g., Amazon Alexa, Google Assistant) to control the circuit breaker using voice commands. For example, "OK Google, turn on the [Device Name]" or "Alexa, turn off the [Device Name]".

7.4 Electricity Metering

The device's display shows real-time voltage (V), current (mA), and accumulated energy (kWh). The app provides a more detailed overview and historical data.

8. Manteniment

• Inspecció periòdica: Periodically check the device for any signs of physical damage, loose connections, or discoloration.
• Neteja: Feu servir un drap sec i suau per netejar l'exterior del dispositiu. No utilitzeu netejadors líquids ni dissolvents.
• Actualitzacions de firmware: Ensure your device's firmware is up to date through the Tuya Smart Life app for optimal performance and security.

9. Solució De Problemes

• El dispositiu no s'encén: Check the main power supply and ensure all wiring connections are secure according to the diagram.
• Problemes de connectivitat Wi-Fi: Ensure your Wi-Fi network is 2.4GHz. Check router distance and signal strength. Try resetting the device's Wi-Fi by holding the 'set up' button until the indicator blinks rapidly, then re-pair with the app.
• Frequent Tripping (Leakage Protection): As noted in the safety section, if the device trips three times due to leakage, it will not auto-reconnect. This indicates a persistent electrical leakage issue. Immediately disconnect power and have a qualified electrician inspect your wiring and connected appliances to identify and fix the fault before manually resetting the breaker.
• Frequent Tripping (Over Voltage/Actual): Check the connected load and ensure it does not exceed the device's rated current (63A) or your set over-current protection limit. Verify the incoming voltage is within the acceptable range (230V nominal). Adjust protection thresholds if necessary, but always within safe operating limits.
• Lectures incorrectes: Ensure the device is correctly wired. If readings appear inaccurate, contact support.

10. Consells d'usuari

• Voltage Compatibilitat: This device is rated for 230V AC. It is not designed for 12V DC applications, such as those found in recreational vehicles or off-grid DC systems. Always verify voltage compatibilitat abans de la instal·lació.
• Protection Scope: The circuit breaker primarily protects the electrical grid and connected loads from over/under voltage, over current, and leakage. While it monitors the circuit where an inverter might be connected, its direct protection is for the circuit itself, not necessarily the internal components of the inverter.
• Integració de la llar intel·ligent: Leverage the scheduling features in the Tuya Smart Life app to automate power management, such as turning off non-essential circuits during off-peak hours or when away from home.
