Battery Mode Diagram
5-2-4. 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 connected.
After UPS has been turned on, if the UPS encounters abnormal situations (over-temperature, overload ...,
etc.), the static transfer switch will perform as a transference of the load from the inverter to the bypass
source with no interruption. If the transference is caused by a recoverable reason, the UPS will turn back to
line mode when abnormal situation has been solved.
