Problem resolving
The site operator or helpdesk is the first response to a customer call. The helpdesk can remotely
solve simple problems for the customer.
In special cases the site operator with knowledge of the charger can be asked by ABB support to
report about the status of some internal components of the charger. Therefore a brief description
of the position and function of these components is described on the next pages.
