Troubleshooting
This section contains information and procedures on how to troubleshoot any faults and errors
that may occur during operation of the charging station.
If you have any problems please follow these steps:

Problems
Possible causes
Solutions
1)
Input
overvoltage
The input voltage on the AC
side may be too high
1.
Check the input voltage from the back-end
2.
If the voltage is higher than 264Vac for a
limited period of time, wait for the grid to
re-establish an adequate voltage value.
2)
Input
overcurrent
The input current on the AC
side may be too high
1.
Check whether there is a low resistance
connection between the AC outputs of the
charger cable
2.
Immediately switch off the circuit breaker
for the leakage current of the power
distribution
3)
Input
overfrequency
The input frequency on the
AC side may be too high
1.
Check the input voltage frequency from
the back-end
2.
If the frequency is higher than 55Hz for a
limited period of time, wait for the grid to
re-establish an adequate value.
