Automatic Bypass Operation
When the abnormalities occurred in the UPS during the normal operation,
the UPS switches to the bypass operation automatically. During the
bypass operation, the UPS sends the input voltage to the output directly
and supplies the electric power to the connected device. In this case, even
if the power failure occurs, the UPS becomes the power failure state
without switching to the battery operation.

Manual bypass operation
Manual bypass operation can be switched to bypass operation during
normal operation. Press the RESET and BYPASS switches
simultaneously for 3 seconds.
Press again for 3 seconds to return to normal operation. In this case, even
if the power failure occurs, the UPS becomes the power failure state
without switching to the battery operation.
