5. Configuración e instalación
Follow these steps for proper installation of the ATS. Ensure all safety precautions are observed.
5.1 Montaxe
- The ATS is designed for 35mm DIN rail mounting.
- Locate a suitable position within your electrical distribution box or enclosure.
- Align the ATS with the DIN rail and press firmly until it clicks into place.

5.2 Diagrama de cableado e conexións
Refer to the wiring diagram below for correct electrical connections. Ensure all connections are tight and secure.
- Source A (PV & Inverter): Connect your primary power source (e.g., solar inverter output) to the terminals labeled 'Source A'.
- Source B (City Power): Connect your secondary power source (e.g., utility grid) to the terminals labeled 'Source B'.
- Load/Output: Connect the electrical load you wish to power to the 'Load' or 'Output' terminals.
- Liñas de control: Connect common power input and control lines as indicated in the diagram.

6. Instrucións de funcionamento
The ATS features a simple control mechanism for selecting between automatic and manual operation.
6.1 Manual/Automatic Switch
- The green toggle switch on the front panel allows you to select the operating mode.
- 'Auto' Position: In this position, the ATS will automatically detect the availability of power from Source A and Source B and switch the load accordingly. It prioritizes Source A (PV & Inverter) if both are available, or switches to Source B (City Power) if Source A fails.
- 'Manual' Position: In this position, you can manually select the desired power source (Source A or Source B) using the manual handle. The automatic transfer function is overridden.
6.2 Indicador de enerxía
- A power indicator light (typically red) is present on the front panel.
- This indicator illuminates to show that the device is receiving power and is operational.

7. Mantemento
Regular maintenance helps ensure the longevity and reliable operation of your ATS.
- Inspección periódica: Annually inspect the ATS for any signs of physical damage, loose connections, or overheating.
- Limpeza: Manteña o dispositivo limpo e libre de po e residuos. Use un pano suave e seco para limpar. Non empregue produtos de limpeza líquidos.
- Comprobación de conexión: Periodically verify that all electrical connections are tight and secure. Loose connections can lead to overheating and malfunction.
- Condicións ambientais: Asegúrese de que o ambiente de funcionamento se manteña dentro dos rangos de temperatura e humidade especificados.
8 Solución de problemas
If you encounter issues with your ATS, refer to the following common problems and solutions:
| Problema | Causa posible | Solución |
|---|---|---|
| Sen enerxía para cargar | Both power sources (A and B) are off; loose wiring; internal fault. | Check if both power sources are active. Verify all wiring connections. If problem persists, contact qualified personnel. |
| ATS does not switch automatically | Switch is in 'Manual' mode; power source not detected; internal fault. | Ensure the switch is set to 'Auto' mode. Verify power is present from the intended source. If problem persists, contact qualified personnel. |
| O indicador de enerxía está apagado | No power supply to the ATS; indicator light failure. | Check incoming power supply to the ATS. If power is present and indicator is still off, contact qualified personnel. |
| Sobrequencemento ou cheiro a queimado | Loose connections; overloaded circuit; internal component failure. | Immediately disconnect all power. Do not attempt to operate. Contact qualified personnel for inspection and repair. |
For issues not listed above or if solutions do not resolve the problem, please contact a qualified electrician or the manufacturer's support.
