4. TROUBLESHOOTING 

 

 

Trouble Name 

Possible Cause 

Troubleshoot Suggestions 

AC over voltage 

AC  input  voltage  is 
higher than standard. 

1.  If instantaneous voltage is over 264Vac

wait for 

the power grid to recover normally. 

2.  Check and analyse background monitoring data. If 

the voltage in this area is over-voltage for a long 
time,  please  increase  the  input  over-voltage 
protection  value  by  the  configuration  software; 
max. value is up to 300Vac. 

3.  If  the  problem  cannot  be  eliminated,  please 

contact us.  

AC under voltage 

AC  input  voltage  is 
lower than standard. 

1.  If instantaneous voltage is under 140Vac, wait for 

the power grid to recover to normal. 

2.  Check and analyse background monitoring data. If 

the voltage in this area is under-voltage for a long 
time,  please  reduce  the  input  under-voltage 
protection  value  by  the  configuration  software; 
min. value is 140Vac. 

3.  If  the  problem  cannot  be  eliminated,  please 

contact us. 

AC over current 

AC  input  current  is 
higher than standard. 

1.  Immediately  disconnect  the  leakage/over-current 

protection circuit breaker of the distribution box. 

2.  Check  whether  there  is  low  impedance  or  short 

circuit between two lines of output line of AC EV 
charging station. 

3.  After the above problems are eliminated, power on 

again.  If  the  problem  still  cannot  be  eliminated, 
please contact us. 

AC over frequency 

AC  input  frequency  is 
higher than standard. 

1.  If instantaneous frequency exceeds 55Hz, wait for 

the power grid to recover to normal. 

2.  Check  the  input  voltage  frequency  in  the 

background monitoring data. If it is too high for a 
long  time,  please  contact  the  power  supply 
department for handling. 

AC under frequency 

AC  input  frequency  is 
lower than standard. 

1.  If the instantaneous frequency is less than 45Hz, 

wait for the power grid to recover to normal. 

2.  Check  the  input  voltage  frequency  in  the 

background monitoring data. If it is too lower for a 
long time, please reduce the protection frequency; 
value, min. value up to 40Hz. 

3.  If  the  problem  cannot  be  eliminated,  please 

contact us.
