3.2.1 Standby Mode
Upon connecting to utility input power, the UPS is in Standby mode before UPS is turned on (if
BYPASS enable setting is Disabled), and charger function will be active when the battery is present.
The load is not powered under this mode.
3.2.2 Line Mode
In Line Mode, the rectifier derives power from the utility power and supplies DC power to the
inverter and the charger charges the battery. The inverter filters the DC power and converts it into
pure and stable AC power to the load.
