Expected Result
● Equalized
charging
voltage: 14.16
V x Number of
batteries
(tolerance:
±1%)
● Float charging
voltage: 13.68
V x Number of
batteries
(tolerance:
±1%)
The deviation
between the
detected
temperature and
the displayed
temperature is
less than 3°C.
7 Routine Maintenance
Troubleshooting
1. If the voltage
drop between
the battery
string output
terminals and
the battery
input terminals
at the UPS side
is greater than
1% of the
battery string
voltage, check
whether the
cable between
the battery
string and the
UPS is
excessively
long, or the
cross-sectional
area of the
cable is
excessively
small.
2. Check whether
the equalized
charging
voltage and
float charging
voltage are
correctly set
for the UPS.
3. If the fault
persists,
contact
technical
support.
1. Install the
battery
temperature
sensor in the
correct
position.
2. Replace the
battery
temperature
sensor.
