2. If the frequency exceeds 55Hz for a short time,
wait till power grid recover to normal voltage range.
AC input frequency may be
too low.
1. Check the input voltage frequency from the
backend.
2. If the frequency is lower than 45Hz for short time,
wait till power grid recover to normal voltage range.
Temperature may be too low
inside the charger.
1. Check the surrounding conditions of chargers
installed whether there is heating device nearby.
Make sure environmental temperature is under 60℃.
Leakage current to the earth
may be too high.
1. Shut off the leakage current protection switch of
power distribution cabinet immediately.
2. Check whether there is broken of AC output cables
or low resistance connection to the earth.
Leakage current
sensor abnormal
Detection of leakage current
sensor is abnormal.
1. Shut off the leakage current protection switch of
power distribution cabinet immediately.
2. Check whether there is broken of AC output cables
or low resistance connection to the earth.
Inappropriate grounding
connection of input/output
cables or inverse connection
of L/N input cables.
1. Shut off the leakage current protection switch of
power distribution cabinet immediately.
2. Check if AC input/output cables are normal, and if
inverse connection of L/N input cables.
Charging cable
connection
abnormal
Poor connection of charging
cable with EV/Charger.
1. Check if charging cable connection is correct and
firm.
Note: If the above problems cannot be solved, please contact the seller.
