3.1.2 Bypass Mode
When the UPS is supplied with AC mains without being turned on,
or in the event of overload or other faults after the UPS is turned on,
the load is supplied by Bypass AC source, which comes directly
from the AC mains input; and meanwhile the charger charges the
battery. When in Bypass mode, the bypass indicator on the front
panel shines green.
Notice
In the event of mains failure or mains voltage outside the range from
120V to 253V in Bypass mode, the UPS is unable to supply the
load.
3.1.3 Battery Mode
When the UPS is in Normal mode, in the event of mains failure or
mains voltage outside tolerances, the rectifier and charger stop
running, the battery begins to discharge and supply the load through
inverter. When the UPS operates in Battery mode, the battery
indicator and inverter indicator on the front panel shine green,
accompanied with a beep every 3 seconds, giving alarm that the
UPS is operating in Battery mode.
