62 Planning the electrical installation
Protecting the converter installation
Protecting the grid cable in short-circuit situations
Equip the cable with fuses. Size the fuses according to local safety regulations,
appropriate voltage and the rated current of the converter.
Protecting the generator and generator cable in short-circuit
situations
The converter protects the generator cable and the generator in a short-circuit situation
when the generator cable is sized according to the nominal current of the converter. No
additional protection devices are needed.
Protecting the converter, generator cable and grid cable against
thermal overload
The converter protects itself, the grid cables and generator cables against thermal
overload when the cables are sized according to the nominal current of the converter and
ambient conditions are within the limits specified under
No additional thermal protection devices are needed.
Protecting the converter against ground faults in the generator or
generator cable
Both the grid-side converter and generator-side converter are equipped with an internal
ground fault protective function to protect them against ground faults in the converter itself,
the generator and generator cable. (This is not a personal safety or a fire protection
feature.) You can disable both ground fault protective functions (not recommended); refer
to the firmware manual.
Protecting the converter against ground faults in the converter or
grid cable
Both the grid-side converter and generator-side converter are equipped with an internal
ground fault protective function to protect them against ground faults in the converter itself
and grid cable. (This is not a personal safety or a fire protection feature.) You can disable
both ground fault protective functions (not recommended); refer to the firmware manual.
