Description
stops if a battery
overtemperature protection
alarm (when the
temperature reaches the high
temperature threshold plus
3°C) is generated.
Single batt. float chg.
voltage deviation alarm
thres. (%) and Single batt.
dis. voltage deviation alarm
thres. (%) are used to check
whether the cells in each
battery string have the same
charge voltage and discharge
voltage. When a value
exceeds the specified range,
an alarm is generated.
The calculation formula is
(Charge/Discharge voltage –
Average voltage)/Average
voltage x 100%.
After this function is enabled,
an alarm is generated if the
configured battery capacity
exceeds the charging
capacity of the rack.
In battery mode, the UPS can
automatically power off
according to the preset
shutdown delay time. If the
parameter is disabled, this
function is not available.
An alarm is generated if this
parameter is set to Enable
and the backup time is less
than the warning threshold.
An alarm is generated if this
parameter is set to Enable
and the remaining capacity is
less than the warning
threshold.
If this parameter is set to
Enable, the intelligent
battery hibernation function
is enabled.
