Check Method and
Troubleshooting
● Inspection method: (1)
Visual inspection. Check
the parameters
displayed on the UPS
LCD. (2) Measure.
Measure the battery
internal resistance
using an internal
resistance tester.
● Troubleshooting: Check
the equalized charging
voltage, float charging
voltage, and internal
resistance of a single
battery. If the battery
charging voltage
exceeds the threshold,
perform a complete
forced equalized
charging for the battery
string and check the
battery string voltage.
● Inspection method: (1)
Visual inspection. Check
the parameters
displayed on the UPS
LCD. (2) Measure. Use
a multimeter to
measure the output
voltage of the battery
string.
● Troubleshooting:
Correct the equalized
charging voltage and
float charging voltage
of the UPS. If the
difference between the
battery string voltage
displayed on the UPS
LCD and the measured
value is greater than
1%, contact technical
support.
