BATTERY CONFIGURATION screen
Recharge type
Recharge type (Lead Acid / NiCd / Boost).
Lead Acid
for:
Sealed battery (VRLA), NiCd without boost-
charge and open battery without boost-
charge.
NiCd
for:
Nickel Cadmium battery with boost-charge.
Boost
for:
O
pen battery with boost-charge.
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):
2.27Vdc for cell
240 cells x 2.27Vdc = 545Vdc
NiCd without boost-charge:
1.41Vdc for cell
386 cells x 1.41Vdc = 545Vdc
NiCd with boost-charge:
1.41 (1.55 boost-charge) Vdc for cell
351 cells x 1.41Vdc = 495 (545) Vdc
Open battery without boost-charge:
2.23Vdc for cell
240 cells x 2.23Vdc = 535Vdc
Open battery with boost-charge:
2.23 (2.35 boost-charge) Vdc for cell
232 cells x 2.23Vdc = 518 (545) Vdc
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
40 blocks / 12Vdc battery
80 blocks / 6Vdc battery
240 blocks / 2Vdc battery
NOTE !
The values indicated above, must be considered as standard values.
The actual programmed values must be the ones defined from the battery manufacturer.
