Table 17. Shutdown Criteria
Criteria Description
Backup Time before Initiating the
Shutdown Procedure
(Shutdown After – Shutdown
Timer)
When the UPS switches to battery power, the card starts the
Shutdown Timer countdown and launches the system shutdown
procedure at the end of the countdown. Select this value carefully so
that users have time to complete their tasks and disconnect without
exceeding battery backup time.
NOTE If this criterion is selected to initiate system shutdown,
automatic system reboot is not guaranteed when power is restored
(for example, power restoration if only this system was shut down).
Initiating the Shutdown
Procedure when the Battery
Level is Lower Than (If Capacity
Under)
When the card detects that the remaining backup time percentage is
less than the configured level, the shutdown sequence starts. By
default, this value is set at 20%.
NOTE The UPS already manages an equivalent parameter for the
end of backup pre-alarm. The card does not accept values less than
that programmed in the UPS. Check the UPS documentation.
Shutdown When Backup Time is
Less Than
When the card detects that the percentage of backup time
remaining is less than the set value, the shutdown sequence starts.
Shutdown Duration Duration (in seconds) required for the system protected by the
protection application to shut down.
The protection application transmits its own shutdown duration to
the ConnectUPS-MS Card.
Based on these values (maximum shutdown duration of all
subscribed customer systems), the card sends the delayed
shutdown order to the UPS.
Figure 54 shows the shutdown sequence.
