5.1.1.1 Backup time before initiating the shutdown procedure
(Shutdown After – Shutdown Timer)
When the UPS switches to battery, the Network Management Card starts the Shutdown Timer countdown and launches
the system shutdown procedure at the end of the countdown.
This value must be chosen so that users have time to complete their tasks and disconnect, without exceeding battery
backup time.
Note 1:
The Network Shutdown Module can also manage its own Shutdown Timer (configurable in the Shutdown Module"set-
up" menu of each Network Shutdown Module) launched when the UPS switches to battery.
Note that if this criterion is selected to initiate system shutdown, automatic system reboot when power is restored is
not guaranteed (e.g. power restoration if only this system was shut down).
5.1.1.2 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 is started.
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.
