Troubleshooting
Possible solution
1. Do a check of the operation
temperature on the product
label. If the ambient tempera-
ture is too high, the EVSE will
decrease the output current
automatically.
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
electrical contractor. Refer to
section 1.12.
