5. Setup and Installation
Proper installation is crucial for the safe and effective operation of the Smart Breaker. It is recommended that installation be performed by a qualified electrician.
5.1 Wiring Connections
- Disconnect Power: Before starting, ensure all power to the circuit is disconnected at the main breaker or fuse box.
- Identify Terminals: The device has clearly marked 'IN' (Input) and 'OUT' (Output) terminals for Line (L) and Neutral (N) connections.
- Connect Input: Connect the incoming Line (L) and Neutral (N) wires from your power source to the 'IN' terminals.
- Connect Output: Connect the outgoing Line (L) and Neutral (N) wires to your protected load (appliances/circuit) to the 'OUT' terminals.
- Secure Connections: Ensure all wire connections are tight and secure to prevent loose contacts and overheating.

5.2 Mounting
The Smart Breaker is designed for DIN rail mounting. Snap the device onto a standard 35mm DIN rail within an appropriate electrical enclosure.
6. Operating Instructions
Once installed and powered, the Smart Breaker will display the current voltage on its digital screen.
6.1 Power On/Off
The device automatically powers on when connected to a live circuit. There is no manual on/off switch for the device itself; control is typically managed by the upstream circuit breaker.
6.2 Voltage Display
The digital display continuously shows the real-time voltage of the circuit. If an over-voltage or under-voltage condition occurs, the device will trip and display an error code or indicator, cutting off power to the load.
6.3 Automatic Recovery
After a fault condition (over-voltage or under-voltage) clears, the device will automatically reset and restore power to the load after the configured recovery delay time has elapsed. A visual indicator may show 'RECOVERY' or similar text during this process.
Figure 6: Self-Recovery. This image illustrates the automatic monitoring and recovery process of the Smart Breaker after detecting a fault.
7. Settings and Adjustments
The Smart Breaker allows for customization of protection parameters using the 'SET', 'Up' (▲), and 'Down' (▼) buttons.
Figure 7: Customizable Protection. This image shows the device's display and buttons used for adjusting voltage protection settings.
7.1 Entering Settings Mode
Press and hold the SET button for a few seconds until the display changes, indicating entry into the settings menu.
7.2 Adjusting Over-Voltage Threshold (Uvo)
- In settings mode, use the ▲ or ▼ buttons to navigate to the 'Uvo' (Over-Voltage) setting.
- Press SET to select it.
- Use ▲ or ▼ to adjust the desired over-voltage cutoff value (e.g., 130V to 150V).
- Press SET again to confirm and save the setting.
7.3 Adjusting Under-Voltage Threshold (Uve)
- Navigate to the 'Uve' (Under-Voltage) setting.
- Press SET to select it.
- Use ▲ or ▼ to adjust the desired under-voltage cutoff value (e.g., 80V to 100V).

9.1 Fault Inquiry
The device can display recent fault records to assist in troubleshooting.
- Press the SET button briefly (do not hold).
- The display will cycle through fault codes such as 'OV' (Over-Voltage), 'UV' (Under-Voltage), 'UL' (Lower-Voltage), 'ER' (Low-Voltage), 'RL' (Under-Voltage).
- Each code indicates a type of fault that has occurred.
Figure 10: Smart Reset Options. This image details the fault inquiry function and the procedure for a factory reset.
9.2 Factory Reset
If you encounter persistent issues or wish to revert all settings to their default values, perform a factory reset.
- Ensure the device is powered on.
- Press and hold the SET button for approximately 5 seconds until the display indicates a reset (e.g., 'RST' or similar).
