6. Operation Principles
6.2.5 Bypass Mode
Upon connecting to utility input power, the UPS is in Bypass Mode before the UPS is turned on (if BYPASS setting is enabled), and charger
function will be active when battery is connected.
If the UPS has been turned on and encounters abnormal situations (over-temperature, overload, etc.), the static transfer switch will
transfer the load from the inverter to the bypass source with no interruption. If the transference was caused by a recoverable reason, the
UPS will return to Line Mode once the situation has been resolved.
