4.1 Montáž
The ATS is designed for 35mm DIN rail mounting. Ensure the DIN rail is securely fastened within your distribution box or electrical panel.

Figure 4: The image illustrates the 35mm DIN rail installation method and the robust terminals for wiring.
4.2 Schéma zapojení
Proper wiring is essential for safe and correct operation. Refer to the diagram below for connecting the common power (I), backup power (II), and load output.

Figure 5: Wiring diagram showing connections for Common N, Common L, Spare N, Spare L, and Load Output. Ensure the input power supply is connected in the correct phase sequence.
5. Návod k obsluze
The DEWIN G2R 63A 2P ATS supports both automatic and manual operation modes.
5.1 Automatický režim
In automatic mode, the switch will detect the presence of the common power supply (I) and the backup power supply (II). If the common power fails, the switch will automatically transfer the load to the backup power supply. When common power is restored, it will switch back.
- Set the 'Auto/Manual' switch to 'Auto'.
- The indicator lights (I and II) will show which power source is active.
- The 'Load ON' indicator will illuminate when power is supplied to the load.
5.2 Ruční režim
To manually switch between power sources:
- Set the 'Auto/Manual' switch to 'Manual'.
- Use the operating handle to physically switch between position I (Common Power) and position II (Backup Power).
- Ensure the desired power source is selected and the corresponding indicator light is on.
6. Údržba
The DEWIN G2R 63A 2P ATS is designed for reliable operation with minimal maintenance. However, periodic checks are recommended:
- Vizuální kontrola: Regularly inspect the device for any signs of physical damage, loose connections, or overheating.
- Čištění: Udržujte zařízení bez prachu a nečistot. K čištění používejte suchý, měkký hadřík. Nepoužívejte tekutiny ani abrazivní čisticí prostředky.
- Kontrola terminálu: Periodically verify that all terminal screws are tight to prevent arcing and ensure good electrical contact.
Před prováděním jakékoli údržby vždy odpojte napájení.
7. Řešení problémů
If you encounter issues with your ATS, consider the following common problems and solutions:
- Žádné napájení k načtení:
- Check if both common and backup power sources are active.
- Verify the 'Load ON' indicator is illuminated.
- Ensure the ATS is in 'Auto' mode or manually switched to an active power source. - Failure to Transfer Automatically:
- Confirm the 'Auto/Manual' switch is set to 'Auto'.
- Check the status of both power sources using their respective indicator lights.
- If the issue persists, consult a qualified electrician. - Overheating or Unusual Noises:
- Immediately disconnect power.
- This could indicate a serious electrical fault. Do not attempt to repair it yourself. Contact a qualified electrician.
