Float voltage
Voltage to maintain battery charging.
Float voltage = Number of battery cells x battery float voltage per cell.
Typical battery float voltage per cell (ask the battery manufacturer for confirmation):
Sealed battery (VRLA):
NiCd without boost-charge:
NiCd with boost-charge:
Open battery without boost-charge:
Open battery with boost-charge:
Recharge current
Maximum battery recharge current.
Max 20% of battery capacity (Ah).
Example: 250Ah - max recharging current 50A.
Autonomy time
The autonomy time of the battery.
UPS autonomy on battery mode at full load condition.
This value is calculated based on the battery type, capacity and number of cells.
Stop Operation time
Residual battery autonomy time before UPS forced shutdown.
Standard set 3 minutes. Settable from 1 minute to autonomy time in minutes (see tables).
Capacity
Ah capacity of the battery.
Cells
Number of cells of the battery, see "Float voltage".
Example: 240 battery cells
NOTE !
The values indicated above, must be considered as standard values.
The actual programmed values must be the ones defined from the battery manufacturer.

240 cells x 2.27Vdc = 545Vdc
386 cells x 1.41Vdc = 545Vdc
351 cells x 1.41Vdc = 495 (545) Vdc
240 cells x 2.23Vdc = 535Vdc
232 cells x 2.23Vdc = 518 (545) Vdc
