6.2 Wiring
- Ensure the main power supply is OFF.
- Connect the incoming power lines (Line and Neutral) to the 'IN' terminals at the top of the device.
- Connect the outgoing load lines (Line and Neutral) to the 'OUT' terminals at the bottom of the device.
- Ensure all connections are tight and secure to prevent loose contacts and overheating.
The connection method is 'Up Input - Down Output'.

7. Operating Instructions
The device features an intuitive interface with 'SET', 'Up', and 'Down' buttons for parameter adjustment and an LED display for real-time monitoring.
Image: LED display screen showing real-time voltage and current.
7.1 Initial Power-on
Upon initial power-on, the smart circuit breaker supports 120V/240V. The default overvoltage setting is 260V and undervoltage is 90V.
7.2 Function Setting Instructions
To adjust parameters, follow these steps:
- Press and hold the SET button for 3 seconds to enter the setting mode. The display will show the current parameter (e.g., Power-on Delay Time).
- Use the Up (▲) and Down (▼) buttons to adjust the value of the displayed parameter.
- Press the SET button briefly to cycle through the different adjustable parameters (A01 to A12).
- After adjusting all desired parameters, press and hold the SET button again for 3 seconds to save the settings and exit the setting mode. The display will show 'SAVE' or similar confirmation.

9. Troubleshooting
This section provides guidance for common issues you might encounter.
9.1 Device Not Powering On
- Check the incoming power supply to ensure it is active.
- Verify all wiring connections are correct and secure.
- Ensure the device has been powered on within one year of purchase, as prolonged unpowered storage can affect internal components.
9.2 Frequent Tripping
- Review your set overvoltage, undervoltage, and overcurrent parameters. They might be set too sensitively for your electrical environment.
- Check the connected load for any faults or excessive current draw.
- Monitor the incoming voltage and current for frequent fluctuations that might be triggering the protection.
9.3 Automatic Recovery Failure
- Ensure the power conditions (voltage and current) have returned to within the safe, set parameters. The device will only recover once stable conditions are detected.
- Check the recovery time setting (e.g., Overvoltage Recovery Time, Undervoltage Recovery Time, Overcurrent Recovery Time) to ensure it is not set to an excessively long duration.
If issues persist after performing these checks, please contact customer support or consult a qualified electrician.
