before setting up a charging schedule for the first time.
Insert the EV charging cable after the schedule is set up.
3 Over-voltage

power input is not sufficient. If the result is less than or
equal to 166.4 V, 80 % of the rated voltage (208 V), contact
local power grid company.
5 Ground fault Ensure the charger is grounded correctly.
