3.2.3 Battery Mode
The UPS automatically transfers to Battery mode if the utility power fails. There is no interruption in
power to the load upon utility power failure.
In battery mode, the rectifier derives power from the battery and supplies DC power to the inverter.
The inverter filters the DC power and converts it into stable pure sinewave AC power to the load.

3.2.4 Bypass Mode
Upon connecting to utility input power, the UPS is in Bypass mode before UPS is turned on (if
BYPASS enable setting is Enabled), and charger function will be active when battery is present.
While UPS operates in line mode, if the UPS detects something abnormal (over-temperature,
overload, and etc.), the UPS will transfer to bypass mode, i.e., disconnect inverter output from the
load and supply power to the load through the static transfer switch. Once the abnormal condition
is gone, the UPS will revert to line mode.
