Over temperature
The temperature inside
of AC EV charger is too
high.
1. Inspect the install environment, check whether
there are other heating equipment nearby, and
ensure the ambient temperature is below 60°C.
2. If the problem cannot be eliminated, please
contact us.
Leakage
current
exceeds
the
standard
Residual
current
is
higher
than
the
standard
1. Immediately disconnect the leakage/over-current
protection switch of the distribution box.
2. Check whether the output line of the AC charging
pile is damaged or has low impedance or a short-
circuit to the ground.
3. If the problem cannot be eliminated, please
contact us.
Earth fault
Input/output
poor
grounding or input L / N
reverse connection
1. Disconnect the distribution box leakage/over-
current protection switch immediately.
2. Check whether the AC pile input/output line is
grounded normally and whether the input L / N is
connected in a normal sequence.
3. After the above problems are eliminated, power on
again. If the problem still cannot be eliminated,
please contact us.
Communication
abnormal
(networking mode)
Poor
background

1. Check whether the connection of the network
cable is correct and reliable.
2. Check if the charging station configuration is
correct in the background.
3. If the problem cannot be eliminated, please
contact us.
