5.2 Fault Code and Resolution
Note: If the above problems cannot be solved, please contact the seller.
Error Code Problems Possible Causes Possible Solutions
OverVolt
Input over
voltage
AC input
voltage may be
too high.
1. Check the input voltage from the backend.
2. If the voltage is over 276V AC for a short
time, wait until the power grid recovers to
normal voltage range.
UnderVolt
Input lower
voltage
AC input
voltage may be
too low.
1. Check the input voltage from the backend.
2. If the voltage is under 184V AC for a short
time, wait until the power grid recovers to
normal voltage range.
OverCurr
Output
overload
AC output
current may be
too large.
1. Shut off the leakage current protection
switch of power distribution cabinet imme-
diately.
2. Check whether there is low resistance
connection between AC output cables of the
charger.
OverFreq
Input over
frequency
AC input
frequency may
be too high.
1. Check the input voltage frequency from
the backend.
2. If the frequency exceeds 63Hz for a short
time, wait until power grid recover to normal
voltage range.
UnderFreq
Input lower
frequency
AC input
frequency may
be too low.
1. Check the input voltage frequency from
the backend.
2. If the frequency is lower than 47Hz for
short time, wait until power grid recover to
normal voltage range.
OverTemp
Over tem-
perature
Temperature
may be too
high inside the
charger.
1. Check the surrounding conditions of
chargers installed whether there is heating
device nearby. Make sure environmental
temperature is under 60°C.
Over DCLeak
Over leak-
age current
Leakage current
to the earth
may be too
high.
1. Shut off the leakage current protection
switch of power distribution cabinet imme-
diately.
2. Check whether there is broken of AC out-
put cables or low resistance connection to the
earth.
PhaseError
Reverse
connection
Reverse con-
nection of L/N
input cable.
1. Shut off the leakage current protection
switch of power distribution cabinet imme-
diately.
2. Check if AC input/output cables are nor-
mal, and if inverse connection of L/N input
cables.
CableRCError
Charging
cable con-
nection
abnormal
Poor connec-
tion of charging
cable with EV/
Charger.
1. Check if charging cable connection is cor-
rect and firm.
