2.2 Operation Mode of the UPS
5
At the bypass operation (In the event of the abnormalities
inside the UPS)
When the abnormalities occur inside the UPS, an output switching circuit switches to a
bypass circuit, and continues to supply electric power through the bypass circuit to the
connection device.
In addition, changeover between circuits can switch without instantaneous interruption.
It is also the same as when switching to the bypass operation manually with the switch
on the front of the UPS.
At the bypass operation, electric power is not supplied (battery operation) from the
battery to the connection device.
