Undertemp. alarm
thresh.(°C)
Battery temperatures can be monitored in a timely
manner. If a battery overtemperature alarm is
generated, the charge current limit value decreases
to 0.03 CA. Battery charging stops if a battery
overtemperature protection alarm is generated
(when the temperature reaches the
overtemperature threshold plus 3°C).

Single batt. float chg. voltage deviation alarm
thres.(%)
and
Single batt. dis. voltage deviation
alarm thres.(%)
are used to check whether the
batteries 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%.

Batt. mode shut
When the mains fails and the UPS transfers to
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.
