Setup and Installation
The EAWCBT-J is designed for 35MM DIN rail installation. Proper wiring is crucial for safe and correct operation.
Wiring Instructions:
- Ensure the main power supply to the circuit is completely off before beginning installation.
- Mount the EAWCBT-J device onto a standard 35MM DIN rail.
- Connect the Live (L) and Neutral (N) wires from the power source to the top terminals of the device. It is critical that power enters from the top.
- Connect the load's Live (L) and Neutral (N) wires to the bottom terminals (OUT L and OUT N) of the device.
- Double-check all connections for tightness and correct polarity.
- Once wiring is complete, restore power to the circuit.

Operating Instructions
The EAWCBT-J can be operated via its physical button or through a dedicated mobile application for remote control and advanced settings.
Initial Power-On:
After successful installation and power restoration, the device will power on. The display will show current status and readings.
Mobile Application Control:
- Download the official NGDOLAOV control application from your smartphone's app store.
- Follow the in-app instructions to pair your EAWCBT-J device. This typically involves putting the device into pairing mode (refer to the device's display or a quick start guide for specific steps).
- Once paired, you can remotely control the on/off state of the circuit breaker.
- Setting Protection Thresholds: Use the app to set the desired values for Current Limit, Power Limit, Overvoltage Protection, Undervoltage Protection, and Temperature Protection. The device will automatically trip if these thresholds are exceeded.
- Timer and Schedule Functions: Program specific times for the device to turn on or off. Recurring timers can be set for daily or weekly schedules.
- Energy Monitoring: View real-time energy consumption (KWh), set electricity prices, and download historical data for analysis.
- Power-On Response: Configure how the device behaves after a power outage. Options include restoring to the last known state, always turning ON, or always turning OFF.
Voice Control:
If integrated with a compatible smart home system (e.g., Amazon Alexa, Google Assistant), you can use voice commands to control the on/off state of the EAWCBT-J. Refer to your smart home system's documentation for integration steps.
Maintenance
The EAWCBT-J is designed for minimal maintenance. Regular checks can help ensure its longevity and proper function.
- Periodically inspect the device for any visible damage or loose connections. Ensure power is off before inspection.
- Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning.
- Do not use abrasive cleaners or solvents.
- Ensure the operating environment remains within the specified temperature range (-25°C to 70°C).
Troubleshooting
If you encounter issues with your EAWCBT-J, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | No power supply; incorrect wiring; device fault. | Check main power supply. Verify wiring connections (L and N, top entry). If issues persist, contact support. |
| Device trips frequently. | Overcurrent, overvoltage, undervoltage, or over-temperature condition; incorrect threshold settings. | Check connected load for faults. Review and adjust protection thresholds in the mobile application. Ensure ambient temperature is within limits. |
| Remote control not working. | No internet connection; app not paired; device not powered. | Ensure your smartphone has internet access. Verify the device is powered on and connected to Wi-Fi. Re-pair the device with the app if necessary. |
| Energy monitoring data is inaccurate. | Incorrect calibration (unlikely for user); device fault. | Ensure the device is correctly installed and handling the full load. If discrepancies persist, contact support. |
