Shutdown CriteriaCriteria DescriptionBackup Time before Initiating theShutdown Procedure(Shutdown After – Shutdown Timer)When the UPS switches to battery power, the card starts the ShutdownTimer countdown and launches the system shutdown procedure at the endof the countdown. Select this value carefully so that users have time tocomplete their tasks and disconnect without exceeding battery backup time.NOTE If this criterion is selected to initiate system shutdown, automaticsystem reboot is not guaranteed when power is restored (for example,power restoration if only this system was shut down).Initiating the Shutdown Procedurewhen the Battery Level is LowerThan (If Capacity Under)When the card detects that the remaining backup time percentage is lessthan the configured level, the shutdown sequence starts. By default, thisvalue is set at 20%.NOTE The UPS already manages an equivalent parameter for the end ofbackup pre-alarm. The card does not accept values less than thatprogrammed in the UPS. Check the UPS documentation.Shutdown When Backup Time isLess ThanWhen the card detects that the percentage of backup time remaining is lessthan the set value, the shutdown sequence starts.Shutdown Duration Duration (in seconds) required for the system protected by the protectionapplication to shut down.The protection application transmits its own shutdown duration to theNetwork Card-MS.Based on these values (maximum shutdown duration of all subscribedcustomer systems), the card sends the delayed shutdown order to the UPS.Battery CapacityUtility FailureShutdown AfterStart of theShutdown SequenceDelay BeforeShutdownUPS Shut Off100%If Remaining Time Under0%Card Parameters UPS ParametersRemaining AutonomyShutdown DurationShutdown IfRemainingCapacity Under
