Manuale di istruzioni

1. Introduzione

This manual provides detailed instructions for the installation, operation, and maintenance of the NPQPNAFC TOQ5-63/4P 3 Phase Din Rail ATS Dual Power Automatic Transfer Switch. This device is designed to automatically switch between two power sources, typically city power and a generator, ensuring continuous power supply to critical loads. It is suitable for applications requiring reliable power transfer without interruption.

The TOQ5 series includes models TOQ5-63/4P, TOQ5-100/4P, and TOQ5-125/4P, with this specific manual focusing on the 63A, 220V variant (TOQ5-63/4P).

2. Informazioni sulla sicurezza

WARNING: Electrical shock hazard. Installation and maintenance must be performed by qualified personnel only. Disconnect all power sources before working on the device.

• Always ensure the main power supply is disconnected before installation or maintenance.
• Verificare che i collegamenti elettrici siano corretti per evitare danni al dispositivo e alle apparecchiature collegate.
• Do not operate the switch in environments with excessive moisture or corrosive gases.
• This device is designed for city power and generator applications only. It is not suitable for PV systems or inverters.
• Assicurare la corretta messa a terra dell'impianto elettrico.

3.2 Caratteristiche

• Compatibilità con doppia fonte di alimentazione: Designed for seamless switching between city power and a generator.
• Trasferimento automatico: Automatically detects power loss and transfers to the backup source.
• Funzionamento manuale: Allows for manual selection of power source when needed.
• Fast Transfer Speed: Switches in less than 8ms, ensuring minimal interruption.
• Montaggio su guida Din: Facile installazione nei quadri elettrici standard.
• PC Level Switch: High reliability and durability.

4. Installazione

Proper installation is crucial for the safe and reliable operation of the ATS. Always ensure power is disconnected before proceeding.

4.1 Montaggio

• Mount the ATS on a standard 35mm Din Rail within an electrical enclosure.
• Garantire un'adeguata ventilazione attorno al dispositivo.
• Secure the device firmly to prevent movement.

4.2 Schema elettrico

Refer to the following diagram for correct wiring connections. All connections must be tight and secure.

Figure 2: Wiring diagram showing connections for Common Power Input (Source A), Backup Power Input (Source B), Common Control Lines, Backup Control Line, and Load Output.

• Fonte A (City Power): Connect the main utility power supply to the 'Source A' terminals.
• Source B (Generator): Connect the generator power supply to the 'Source B' terminals.
• Lato di carico: Connect the load circuits to the 'Load Side' terminals.
• Linee di controllo: Connect the common control lines and backup control line as indicated in the diagram for automatic operation.
• Ensure all wire gauges are appropriate for the current rating (63A) and local electrical codes.

5. Istruzioni per l'uso

L'ATS offre sia modalità operative automatiche che manuali.

Figure 3: Detail of the manual handle and the manual/automatic selector switch on the ATS.

Modalità operative 5.1

• Modalità automatica: Set the selector switch to 'Auto'. In this mode, the ATS will automatically detect the presence of power from Source A (City Power). If Source A fails, it will automatically transfer the load to Source B (Generator). When Source A is restored, the ATS will automatically switch the load back to Source A.
• Modalità manuale: Set the selector switch to 'Manual'. Use the red manual handle to physically switch between Source A and Source B. The manual operation must be in the 'Main' or 'Source B' position. This mode is typically used for testing or in situations where automatic transfer is not desired.

6. Manutenzione

Una manutenzione regolare garantisce la longevità e l'affidabilità del tuo ATS.

• Ispezione visiva: Ispezionare periodicamente il dispositivo per verificare la presenza di eventuali segni di danni fisici, collegamenti allentati o surriscaldamento.
• Pulizia: Mantenere il dispositivo libero da polvere e detriti. Utilizzare un panno asciutto e morbido per la pulizia. Non utilizzare liquidi o detergenti abrasivi.
• Verifica della connessione: Ensure all terminal connections remain tight. Loose connections can cause overheating and device failure.
• Prova di funzionalità: Testare periodicamente la funzione di trasferimento automatico simulando un'interruzione di correntetage (if safe to do so and with proper precautions).

7. Risoluzione Dei Problemi

If you encounter issues with your ATS, refer to the following common troubleshooting steps:

• Nessun trasferimento di potenza:
  • Check if both Source A and Source B have power.
  • Ensure the selector switch is in 'Auto' mode for automatic transfer.
  • Verify all control wiring connections are correct and secure.
• Surriscaldamento:
  • Verificare la presenza di collegamenti dei terminali allentati.
  • Ensure the load current does not exceed the device's rated current (63A).
  • Verificare che vi sia una ventilazione adeguata attorno al dispositivo.
• Il dispositivo non risponde:
  • Ensure all power sources are connected and active.
  • If in manual mode, ensure the handle is fully engaged in either Source A or Source B position.

If problems persist after attempting these steps, contact qualified electrical personnel or NPQPNAFC customer support for assistance.
