Specifiche tecniche

Precauzioni di sicurezza

Always adhere to local electrical codes and safety regulations during installation and operation. Improper installation can lead to electric shock, fire, or equipment damage. Only qualified personnel should perform installation and maintenance.

• Scollegare l'alimentazione: Assicurarsi che tutte le fonti di alimentazione siano scollegate prima dell'installazione, del cablaggio o della manutenzione.
• Messa a terra corretta: Verify that the device and associated electrical systems are properly grounded.
• Voltage Compatibilità: Confermare che il vol. operativotage of the switch (220V) matches your electrical system.
• Connessioni sicure: All wiring connections must be tight and secure to prevent overheating or arcing.
• Condizioni ambientali: Install the switch in a dry, well-ventilated area, away from flammable materials and excessive heat.

Fasi di installazione

Per una corretta installazione, seguire questi passaggi:

1. Place the automatic transfer switch on a suitable debugging platform. Connect the corresponding power lines ensuring the correct phase sequence. The phase line and the neutral line must be connected accurately to their designated positions to avoid incorrect wiring.
2. When installing a three-pole switch, ensure that both the common and spare neutral wires are correctly connected to their respective neutral terminals (NN and RN).
3. Set the dual-power automatic transfer switch to operate in the self-turning and self-resetting mode. If both power supplies are normal, the switch should default to the common power supply position, and the common power supply should be active.
4. In the event of a phase failure in the common power supply (NA, NB, NC, NN), the dual power supply should automatically switch to the backup power supply. Once the common power supply returns to normal, the switch will automatically revert to the common power supply.
5. To test under-voltage conditions, adjust the voltage of any phase of the common power supply to a predetermined under-voltage value. The dual power supply should then automatically switch to the standby power supply. When the normal power supply voltage is restored, the switch will return to the normal power supply.

Operazione

The LiebeWH ZGQ5-100/2P supports both manual and automatic operation modes. Use the selector switch located on the device to choose your desired mode.

• Modalità automatica (Auto): In this mode, the device continuously monitors both the normal and backup power sources. It will automatically switch to the backup power supply if the normal supply fails or experiences an issue, and then switch back to the normal supply once it is restored.
• Manual Mode (Manual): This mode allows for manual control over the power source selection. The user must physically operate the switch handle to transfer power between the normal and backup sources. This mode is typically used for testing or specific maintenance procedures.

Manutenzione

To ensure the longevity and optimal performance of your LiebeWH ZGQ5-100/2P Automatic Transfer Switch, regular maintenance is recommended.

• Ispezione periodica: Regularly inspect all wiring connections for tightness. Loose connections can cause overheating and potential hazards.
• Pulizia: Keep the device free from dust, dirt, and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Controllo ambientale: Assicurarsi che l'ambiente di installazione rimanga entro gli intervalli di temperatura e umidità specificati.
• Controllo professionale: It is advisable to have the unit inspected by a qualified electrician periodically, especially in critical applications.

Importante: Always disconnect all power sources to the transfer switch before performing any cleaning or inspection.

Risoluzione dei problemi

Problemi comuni e soluzioni

• Issue: No automatic transfer between power sources.

  Soluzione: Verify that the switch is set to "Auto" mode. Check both the normal and backup power sources for proper voltage and secure connections. Ensure that the control wiring is correctly installed according to the diagram.

• Issue: Power interruption or flickering during transfer.

  Soluzione: Ensure all wiring connections are tight and secure. While the transfer time is designed to be fast, highly sensitive electronic equipment may require additional Uninterruptible Power Supply (UPS) protection to bridge the brief transfer period.

• Issue: Unusual or loud noise during switching.

  Soluzione: A distinct clicking sound is normal during the mechanical transfer operation. If the noise is excessively loud, continuous, or accompanied by other unusual sounds, inspect for loose components or consult a qualified electrician. Ensure the device is securely mounted.
• Issue: Device fails to operate or shows no power indication.

  Soluzione: Disconnect all power immediately. Check the main power input and backup power input for voltage presence. Verify all fuses or circuit breakers in the power lines. If the issue persists, do not attempt repairs if unqualified. Contact a certified electrician for inspection and repair.

Scenari applicativi
