6.5.2 Extension of the Deactivation Limits
The deactivation criteria (voltage, frequency) are specified via country parameters.
The inverters have the additional country data set "MVtgDirective/Medium-Voltage Directive
(Germany)". This parameter expands the deactivation limits of the inverter for voltage and frequency
to a maximum/minimum. This country setting may only be selected if the plant or the inverter is
operated with external three-phase decoupling protection, which will automatically disconnect the
inverter from the electricity grid if non-permissible voltage and frequency values occur.
Device protection is still guaranteed.
DANGER!
Electric shock due to missing external decoupling protection.
If you set the country data set "MVtgDirective/Medium-Voltage Directive (Germany)", you
may only operate the inverter with external 3-phase decoupling protection. Without
external three-phase decoupling protection, the inverter will not disconnect from the
electricity grid when the standard requirement is exceeded.
• Install external 3-phase decoupling protection.
