Possible reason
Troubleshooting suggestion
Over voltage
AC input voltage may
be too high
1. Check the input voltage from background monitoring
data
2. If the voltage is over 480Vac in short time，wait till
power grid recover to normal voltage range or Power off
and restart
4. If the fault can not be removed,please contact to us
Under voltage
AC input voltage may
be too low
1. Check the input voltage from background monitoring
data
2. If the voltage is under 140Vac in short time，wait till
power grid recover to normal voltage range or Power off
and restart
4. If the fault can not be removed,please contact to us
Over current
AC input current may
be too big
1. Shut off distribution cabinet leakage/over current
protection switch immediately
2. Check whether there is low resistance connection
between two AC output wires
3. Eliminate above reasons,connect on power again,if
the fault keep on,please contact to us
EPO fault
The emergency stop
button is pressed
1. Reset emergency stop button(On the right side of
the charging station)
Over Leakage
leakage current to earth
may be too high
1. Shut off distribution cabinet leakage/over current
protection switch immediately
2. Check whether there is broken of AC output wires or
low resistance connection to earth
3. Eliminate above reasons,connect on power again,if
the fault keep on,please contact to us
NE fault
Input/output imperfect
earth or inverse
connection for L/N
wires
1. Shut off distribution cabinet leakage/over current
protection switch immediately
2. Check AC input/output wires if be normal,or if
inverse connection input with L/N wires
3. Eliminate above reasons,connect on power again,if
the fault keep on,please contact to us
Display indication
When a problem occurs, error messages
are often shown on the display. With this
information you can quickly identify and
