Input Power Failure

During an Input Power Failure, the UPS inverter will be powered by the UPS batteries. The
following will be displayed on the main and measurement screen (Indication of battery
operation and remaining battery time).

Figure 4-12 Main Screen (On Battery)

The LCD will display a battery low voltage message when the battery capacity is near
depletion. The End of Battery Discharge announcement is displayed when the battery end
voltage is reached. At this time, the inverter will perform an electronic shutdown to prevent
battery loss of life typical from extreme deep discharge conditions and transfer to bypass if
available. When the input power is restored, the inverter will automatically restart to power
the load, and the batteries will be simultaneously recharged. If DC voltage reaches the cutoff
voltage chosen for the DC power supply, the internal DC contactor will open. The End of
Battery announcement is shown at the bottom of the screen.
