Bypass Mode
In Bypass Mode, power is directly routed from the mains power to connected
equipment, bypassing internal converters and without regulation. If the controller
detects the mains is abnormal, it will shut off the output to protect the load.
The “bYPA” code status and beep once every 2 minutes indicates the UPS is
working Bypass Mode. Information about the utility power, the battery level, the
UPS output and the load level will be displayed.
Note:
If mains power fails while in Bypass Mode, the UPS
will not
switch over to
Battery Mode. Connected equipment will not have battery backup protection in
this mode, or be protected from power surge and sags.
