Setting the Country Code and the Menu Language
When switching on for the first time an initial configuration is necessary.
The country code defines the country-specific grid monitoring parameters. The menu language is
automatically set when the country code is selected. The menu language can subsequently be selected as
desired at any time, independent of the country abbreviation set in the menu. The country code is not set on
delivery.
NOTICE
The selected country code can only be changed by service personnel.
After the initial setting and confirmation of the country code the country code can
only be altered within 40 hours. This is also valid for replacement devices. The
country code can then only be changed by authorized service personnel.
