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.

(°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.

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
