By default, this value is set at 20%.
This ratio is equal in % to :
Current autonomy time / Autonomy time announced at the beginning of the UPS on battery sequence

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.
