The following illustration graphically shows the battery discharge process at full load
conditions.
6.3 Battery Low Voltage Tolerances
Excessive discharge will cause the UPS system's battery voltage to drop bellow tolerable
levels. The chart shown below lists the voltage level at which each UPS unit's low-voltage
alarm will sound, and also at what level the low-voltage condition will cause the unit to
automatically shut down.
75kVA 100kVA
Nominal Voltage 240Vdc 324Vdc
Alarm Voltage 228Vdc 308Vdc
Shutdown Voltage min. 210Vdc 283Vdc
6.4 Battery Recharging
The illustration below shows a graphical representation of the UPS battery recharge process
after a full discharge.
