7.2 Configuring the Country Data Set
Set the country data set appropriate for your country or purpose within the first ten feed-in hours via
the rotary switches in the inverter. After the first ten feed-in hours, the country data set can only be
changed by means of a communication product.
Country data set for operation with external decoupling protection
When operating the PV system with external decoupling protection, the inverter has the
additional country data set
Medium-Voltage Directive (Germany)
. This country data set
allows you to extend the operating range of the inverter for voltage and frequency. This
country data set should only be selected if the PV system is disconnected via external
decoupling.
• If you set the country data set for operation with external decoupling protection, you must
only operate the inverter with an external three-phase decoupling protection. Without
external three‑phase decoupling protection, the inverter will not disconnect from the utility
grid when the country-specific standard requirement is exceeded.
