Introduzione
This manual provides essential information for the safe and efficient installation, operation, and maintenance of the Hager ST310 Safety Transformer. Please read these instructions carefully before installation and retain them for future reference.
The Hager ST310 is a durable and robust safety transformer designed to convert 230V AC input to 24V AC output, with a power rating of 20VA. It is a 4PLE (4-module) device, suitable for various electrical applications requiring a safety extra-low voltage (SELV) supply.
Informazioni sulla sicurezza
WARNING: Electrical shock hazard. Installation and maintenance must be performed by qualified personnel only. Disconnect power before working on the transformer or connected circuits.
- Rispettare sempre i codici e le normative elettriche locali e nazionali.
- Ensure the transformer is installed in a dry, well-ventilated area, free from corrosive gases and excessive dust.
- Non superare il volume di ingresso specificatotage (230V) or output load (20VA).
- Assicurare una corretta messa a terra ove necessario.
- Do not open or attempt to repair the transformer. Refer servicing to qualified personnel.
Configurazione e installazione
The Hager ST310 safety transformer is designed for DIN rail mounting within an electrical enclosure.
Disimballaggio e ispezione
Carefully remove the transformer from its packaging. Inspect for any signs of physical damage. If damage is found, do not install the unit and contact your supplier.
Montaggio
- Ensure the main power supply is disconnected at the circuit breaker.
- Locate a suitable position on the DIN rail within your electrical panel. The transformer occupies 4 module units.
- Clip the transformer onto the DIN rail, ensuring it is securely fastened.
Collegamenti elettrici
Refer to the wiring diagram on the transformer casing for precise terminal identification. The ST310 typically features primary (input) and secondary (output) terminals.
- Primary Side (Input): Connect the 230V AC supply to the designated input terminals. Ensure correct phase and neutral connections.
- Secondary Side (Output): Connect the 24V AC load to the designated output terminals. Ensure the total load does not exceed 20VA.
- Use appropriate wire gauges for all connections, suitable for the current ratings.
- Serrare saldamente tutte le viti dei terminali per evitare collegamenti allentati, che potrebbero causare surriscaldamento o funzionamento intermittente.

Operazione
Once the transformer is correctly installed and wired, operation is straightforward.
- After completing all wiring and safety checks, restore power to the circuit.
- The transformer will immediately begin converting the 230V input to 24V output.
- Verificare l'uscita voltage with a multimeter if necessary to ensure correct operation before connecting sensitive equipment.
Condizioni operative normali
- The transformer may become warm during operation, which is normal. However, excessive heat indicates an overload or fault.
- Ensure adequate ventilation around the transformer to dissipate heat.
Manutenzione
The Hager ST310 safety transformer is designed for long-term, maintenance-free operation under normal conditions.
Controlli periodici
- Ispezione visiva: Periodically inspect the transformer for any signs of physical damage, discoloration, or loose connections.
- Rimozione della polvere: Ensure the ventilation openings are free from dust and debris to maintain proper cooling. Use a soft brush or compressed air for cleaning.
- Integrità della connessione: With power disconnected, periodically check the tightness of all terminal screws.
ATTENZIONE: scollegare sempre l'alimentazione prima di eseguire qualsiasi operazione di manutenzione o ispezione.
Risoluzione dei problemi
Questa sezione fornisce soluzioni ai problemi più comuni. Per problemi non elencati qui, contattare personale di assistenza qualificato.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessun volume di uscitatage | Nessun volume in ingressotage; Blown fuse (external); Loose connections; Internal fault. | Check input power supply; Check external fuses; Verify all wiring connections; If problem persists, replace unit. |
| Surriscaldamento del trasformatore | Overload on secondary side; Insufficient ventilation; Short circuit in load. | Reduce load to within 20VA; Ensure adequate airflow; Check load for short circuits. |
| Volume di uscita non correttotage | Input errato voltage; Faulty transformer. | Verificare il volume immessotage is 230V AC; If input is correct, replace unit. |
