5. Mode d'emploi

The Generac RXG16EZA3 Automatic Transfer Switch operates automatically in conjunction with a compatible Generac standby generator. No manual intervention is typically required during a power outage.

Opération automatique:

1. Utility Power Present: Under normal conditions, the transfer switch connects your essential circuits to the utility power source.
2. Utility Power Loss: When the transfer switch detects a loss of utility power, it signals the standby generator to start.
3. Generator Power Transfer: Once the generator reaches its operating speed and voltage, the transfer switch automatically disconnects from utility power and connects your essential circuits to the generator power.
4. Utility Power Restoration: When utility power is restored, the transfer switch monitors the utility source for a stable return.
5. Return to Utility: After a pre-set delay, the transfer switch automatically disconnects from generator power and reconnects to utility power. It then signals the generator to cool down and shut off.
