Value Range
0 hours or a value only in the
range of 16–48 hours. If the time
is set to 0 hours, battery
discharge protection is not
implemented.
EOD restart
If the mains is not functioning
normally, the UPS will transfer
to battery mode. When batteries
reach the EOD threshold, the
bypass is disabled, and EOD
restart is Enable, the UPS will
restart as soon as the mains
resumes.
If EOD restart is disabled, clear
the alarm manually or enable the
restart function for the UPS.

EOD restart
delay (min)
If EOD restart is set to Enable,
the UPS starts working after the
time set for EOD restart delay
when the input recovers from the
power failure upon EOD.

(°C)
Battery temperatures can be
monitored in a timely manner. If
a battery overtemperature alarm
is detected, the charging current
limit decreases to 0.03 CA.
Battery charging 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%.
