At the 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
connection device. In this operation state, even if the power failure occurs, the UPS
becomes the power failure state without switching to the battery operation.
