3.2 Wiring Diagram
Follow the wiring diagram carefully to ensure correct and safe installation. The device should be connected in series with the Live (L) and Neutral (N) lines of the circuit it is protecting.
Figure 3: Wiring diagram and display modes. This image provides two key pieces of information. The upper section demonstrates how the device's digital display cycles through various measurements, including kilowatt-hours (kWh), prepaid power values, power factor (cosφ), and instantaneous power (kW). The lower section presents a clear wiring diagram, showing how the Multi-Function Protector should be integrated into an electrical circuit, connecting between a main power switch and an air circuit breaker, with clearly marked Live (L) and Neutral (N) terminals.
- Connect the incoming Live (L) wire to the 'L' terminal on the device.
- Connect the incoming Neutral (N) wire to the 'N' terminal on the device.
- Connect the outgoing Live (L) wire to the load from the device's 'L' output terminal.
- Connect the outgoing Neutral (N) wire to the load from the device's 'N' output terminal.
- Ensure all connections are tight and secure.

- Energy consumption history and statistics.
- Setting over-voltage, under-voltage, over-current, and leakage protection thresholds.
- Scheduling and timer functions.
5. Maintenance
- Regularly check all wiring connections for tightness and signs of wear.
- Clean the device's exterior with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Ensure the area around the device is free from dust and debris to prevent overheating.
6. Troubleshooting
6.1 Common Issues
- Device not powering on: Check main power supply and wiring connections. Ensure the circuit breaker is not tripped.
- No display: Verify power supply. If power is present, the device may require service.
- WiFi connection issues: Ensure the device is within range of your WiFi router. Check router settings and ensure it's on a 2.4GHz network. Re-pair the device with the app if necessary.
- Incorrect readings: Verify wiring is correct according to the diagram. Ensure the device is rated for the connected load.
- Device trips frequently: This indicates an over-current, over-voltage, under-voltage, or leakage fault. Check connected appliances for faults. Adjust protection thresholds in the app if necessary, but always prioritize safety.
