5. Nastavení a instalace
Proper installation is crucial for the safe and reliable operation of the ATS. Refer to the wiring diagram and follow local electrical codes.
Kontrola před instalací:
- Before installation, carefully inspect the integrity of the ATS for any physical damage.
- Use the operating handle to manually open or close the ATS. Check the flexibility of the internal transmission device.
- Test the generation and disconnection conditions of the load for both the normal and standby power supply in each phase to ensure proper functionality before final wiring.

Kroky instalace:
- Mount the ATS securely in a suitable enclosure, ensuring adequate ventilation and clearance.
- Connect the normal power supply (e.g., grid power) to the designated 'Normal Power A' input terminals.
- Connect the standby power supply (e.g., PV inverter or generator) to the designated 'Reverse Power B' input terminals.
- Connect the load to the output terminals of the ATS.
- Connect the control lines as per the wiring diagram. Ensure all connections are tight and secure.
- Double-check all wiring for correctness and adherence to safety standards before applying power.
6. Návod k obsluze
The NLQ3-125/2P ATS can operate in both automatic and manual modes.
Automatický režim:
- Set the selector switch on the device to 'Auto'.
- In this mode, the ATS will automatically monitor the normal power supply.
- If the normal power supply fails or falls outside acceptable parameters, the ATS will automatically switch the load to the standby power supply within milliseconds.
- When the normal power supply is restored, the ATS will automatically transfer the load back to the normal power supply.
Manuální režim:
- Set the selector switch on the device to 'Manual'.
- In manual mode, the user can use the operating handle to switch between 'Normal Power A' and 'Reverse Power B' as needed.
- This mode is typically used for testing, maintenance, or in situations where automatic transfer is not desired.
