Operation

In this example, power is available from the normal and bypass sources, as well as from the battery.
Notice that the switching devices are all closed except for the bypass switch at the top. The load is
operating on conditioned power from the inverter. The battery is being charged by the rectifier. The
static switch is operative and ready to respond to momentary demands for overload current.
Figure 11 Mimic display screen example: utility fail
In this example, we see that a utility failure has shut down both the normal and bypass power
sources. The battery is connected and supplying power to the load.
