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 cable
diameter is
excessively small.
2. Check whether the
equalized charge
voltage and float
charge voltage are
correctly set for the
UPS.
3. If the fault persists,
contact the
technical support
personnel.
1. Install the battery
temperature sensor
in the correct
position.
2. Replace the battery
temperature sensor.
Set parameters
correctly.
