Problem
The current is too
high
The AC input volt-
age is too high or
too low
There is a failure in
the electrical con-
nections
The EVSE is over-
heated
There seems to be
residual current in
the charging circuit
38
Possible cause
There is an overload on the
EV side
The line and neutral wires
are reversed.
The ambient temperature
exceeds the operation
temperature specification
AC power supply input
voltage is too high
Internal charger malfunc-
tion
The monitoring sensor for
residual current has a fail-
ure.
Possible solution
Contact your local representative
of the manufacturer or a qualified
electrical contractor. Refer to sec-

The EVSE will decrease the cur-
rent output.
1. Do a check of the operation
temperature on the type
plate.
2. If it is necessary, install the
EVSE in an environment with a
lower ambient temperature.
3. Do the procedure that is de-
scribed for the problem 'the
AC input voltage is too high'.
4. If you can not solve the prob-
lem, do not use the EVSE.
Contact your local company
representative or a qualified
