4. Configuration et installation

Follow these general steps for installing the automatic transfer switch. Consult a qualified electrician for specific wiring diagrams and local code compliance.

1. Montage: Securely mount the ATS in a suitable enclosure or panel, ensuring adequate ventilation and clearance for wiring.
2. Coupure de courant : Ensure all power sources (normal and backup) are completely disconnected and locked out before proceeding with wiring.
3. Normal Power Connection: Connect the normal power source (utility) to the designated 'Normal Power' terminals (labeled 'N' on the device). Ensure correct phase and neutral connections.
4. Backup Power Connection: Connect the backup power source (e.g., generator) to the designated 'Backup Power' terminals (labeled 'R' on the device). Ensure correct phase and neutral connections.
5. Connexion de charge : Connect the electrical load (circuits to be powered) to the 'Load' terminals of the ATS.
6. Câblage de contrôle : Connect any necessary control wiring for automatic operation, if applicable.
7. Vérification: Vérifiez minutieusement que tous les branchements électriques sont bien serrés et corrects.

5. Mode d'emploi

The Tbest Automatic Transfer Switch offers both automatic and manual operation modes.

5.1 Sélection du mode

The switch features a selector for operating mode:

• Mode automatique: When the selector is set to 'Auto', the switch will automatically transfer the load between the normal and backup power sources based on power availability. If normal power fails, it will switch to backup. When normal power returns, it will switch back.
• Mode manuel : When the selector is set to 'Manual', the transfer switch will remain in its current position until manually operated.

5.2 Manual Transfer

In 'Manual' mode, or for testing purposes, the large blue 'Direction' handle can be used to manually switch between power sources:

• Rotate the handle towards 'N' (Normal power) to connect the load to the normal power source.
• Rotate the handle towards 'R' (Backup power) to connect the load to the backup power source.

6. Entretien

Regular maintenance ensures the longevity and reliable operation of your ATS.

• Inspection visuelle : Periodically inspect the switch for any signs of damage, loose connections, or overheating.
• Nettoyage: Keep the switch free from dust and debris. Use a dry, non-conductive cloth for cleaning.
• Vérification de la connexion : Annually, or as needed, verify that all electrical connections are tight and secure.
• Test fonctionnel : Periodically test the automatic transfer function by simulating a normal power outage (if safe to do so) to ensure it switches correctly to backup power and back.
