4.1 Operation Modes

The UPS is a double-conversion on-line UPS that may operate in the following alternative modes:

4.1.1 AC Line Mode

The rectifier/charger derives power from the AC mains and supplies DC power to the inverter while floating and boosting charge
to the battery simultaneously. Then, the inverter converts the DC power to AC and supplies to the load.

4.1.2 Battery Mode (Stored Energy Mode)

If the AC mains input power fails, the inverter, which obtains power from the battery, supplies the critical AC load. There is no
power interruption to the critical load. The UPS will automatically return to Normal Mode when AC recovers.
