4. Opsætning og installation
Follow these steps for proper installation of your automatic transfer switch:
- Kontrol før installation: Before installation, carefully inspect the integrity of the ATS unit. Use the operating handle to manually switch it on or off to check the flexibility of the transmission device. Verify the generation and disconnection conditions of both normal and backup power loads at each stage.
- Montering: The switch is designed for easy installation using the standard 35mm DIN rail method, typically within a PZ30 distribution box. Ensure the mounting is secure and stable.
- Ledningsføring: Wire the ATS according to the provided wiring diagram. Ensure all connections are tight and secure to prevent loose contacts and potential hazards.

5. Betjeningsvejledning
The NLQ3-125/2P ATS offers both automatic and manual operation modes to manage power transfer between your main and backup power sources.
5.1 Automatisk tilstand
In automatic mode, the switch continuously monitors the main power supply. If the main power fails or experiences an abnormality, the ATS will automatically switch the load to the backup power source within milliseconds. When the main power is restored, the switch will automatically transfer the load back to the main power supply.
5.2 Manuel tilstand
The device also allows for manual switching between power sources using the operating handle. This mode is useful for testing or specific maintenance scenarios. Ensure the switch is in the 'Manual' position before attempting to manually transfer power.

6. Vedligeholdelse
To ensure optimal performance and longevity of your Sonew NLQ3-125/2P ATS, regular maintenance is recommended:
- Kontrollér regelmæssigt alle ledningsforbindelser for tæthed og tegn på slid eller korrosion.
- Hold enheden ren og fri for støv og snavs.
- Sørg for korrekt ventilation omkring enheden for at forhindre overophedning.
- Test the automatic transfer function periodically by simulating a main power failure (if safe to do so and with proper precautions).
7. Fejlfinding
If you encounter issues with your automatic transfer switch, consider the following:
- Ingen kraftoverførsel: Check if both main and backup power sources are active. Verify all wiring connections are secure. Ensure the switch is in 'Auto' mode if automatic transfer is desired.
- Intermitterende drift: Inspect for loose connections or damaged wiring. Ensure the control voltage er stabil og inden for det angivne område.
- Overophedning: Check for proper ventilation and ensure the unit is not overloaded beyond its rated current.
For persistent issues, please contact customer support or a qualified electrician.
