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.
5.1.1.3 Shutdown when backup time is less than
When the Network Management Card detects that the percentage of backup time remaining is less than the value set, the shutdown
sequence is started.
5.1.1.4 Shutdown duration
Duration (in seconds) required for the system protected by the Shutdown Modules to shut down.
The Network Shutdown Modules transmit their own "Shutdown duration" to the Network Management Card.
Based on these values (maximum Shutdown duration of all subscribed customer systems) that the card will send to the delayed shutdown
order to the UPS.
5.1.2 Controlled outlets
Certain UPS models are equipped with controlled outlets (generally 2) which are always dependant on the UPS's main outlet.
Shutdown of the main outlet systematically causes shutdown of the programmable outlets.
The following notations are used to identify these outlets:
