Problems
Possible Causes
Solutions
Input over voltage
AC input voltage may be too
high.
1. Check the input voltage from the backend.
2. If the voltage is over 276Vac for a short time，wait
till the power grid recovers to normal voltage range.
Input lower voltage
AC input voltage may be too
low.
1. Check the input voltage from the backend.
2. If the voltage is under 184Vac for a short time,
wait till the power grid recovers to normal voltage
range.
Input over current
AC input current may be too
large.
1. Shut off the leakage current protection switch of
power distribution cabinet immediately.
2. Check whether there is low resistance connection
between AC output cables of the charger.
Input over
frequency
AC input frequency may be
too high.
1. Check the input voltage frequency from the
backend.
