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. When the input
power is restored, in a single UPS module system, the inverter will automatically restart to power the load, and the
batteries will be simultaneously recharged. Manual restart will be required in a multi-module system (MMS). The End
of Battery announcement is shown at the bottom of the screen.
