5. Configurazione e installazione
Follow these steps for proper installation of the ATS. Ensure all safety precautions are observed.
5.1 Montaggio
- 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 Schema elettrico e collegamenti
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.
- Linee di controllo: Connect common power input and control lines as indicated in the diagram.

6. Istruzioni per l'uso
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 Indicatore di alimentazione
- 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. Manutenzione
Una manutenzione regolare contribuisce a garantire la longevità e l'affidabilità del tuo ATS.
- Ispezione periodica: Annually inspect the ATS for any signs of physical damage, loose connections, or overheating.
- Pulizia: Mantenere il dispositivo pulito e privo di polvere e detriti. Utilizzare un panno asciutto e morbido per la pulizia. Non utilizzare detergenti liquidi.
- Verifica della connessione: Periodically verify that all electrical connections are tight and secure. Loose connections can lead to overheating and malfunction.
- Condizioni ambientali: Assicurarsi che l'ambiente operativo rimanga entro gli intervalli di temperatura e umidità specificati.
8. Risoluzione Dei Problemi
Se riscontri problemi con il tuo ATS, fai riferimento ai seguenti problemi comuni e alle relative soluzioni:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessuna potenza da caricare | 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. |
| L'indicatore di alimentazione è spento | 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. |
| Surriscaldamento o odore di bruciato | 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.
