- As this product does not have an isolation function, always disconnect the superior Miniature Circuit Breaker (MCB) before performing any maintenance or inspection on the device.
5.3. Disposal of Electrical Waste
All electrical waste should be disposed of in compliance with current WEEE (Waste Electrical and Electronic Equipment) regulations. Do not dispose of with general household waste.
6. Troubleshooting
- Device not powering on: Check the main power supply and ensure all wiring connections are secure according to the wiring diagram (Figure 4).
- Load not turning on/off: Verify the manual control function by pressing the Down/Power button. Check if any fault indicators (>U, <U, >I) are active.
- Fault indicator active: The device is protecting against an overvoltage, undervoltage, or overcurrent condition. Check the connected load and power supply for issues. If automatic fault reset is off, use the Down/Power button for manual reset.
- WiFi connection issues (GPS8-06 only):
- Ensure your WiFi network is 2.4GHz.
- Check the WiFi indicator status (Figure 6): flashing means waiting for configuration, solid means connected, off means unable to connect.
- Try reconfiguring WiFi by holding the Up/WiFi button for 5 seconds.
- Ensure the device is within range of your WiFi router.
- Incorrect parameter settings: Refer to the 'Parameter setting' flowchart and table (Figure 4) to reconfigure values. Remember to save changes by holding the M button for 3 seconds.
- Device unresponsive: Try performing a factory reset (power off, then hold Up and Down buttons while powering on).
7. User Tips
- For quick adjustments during parameter setting, use a long press on the Up or Down buttons.
- If you accidentally enter the setting mode, you can exit without saving by not operating any key for 60 seconds, or by pressing and holding the M button for 3 seconds.
- Regularly monitor your electricity consumption via the display or the app (for GPS8-06) to identify potential energy savings.
