1.6 Nomenclature / Type code
The NORDAC SK 750E frequency inverter has a nomenclature with the same structure as for other NORDAC
frequency inverters. The information contained therein can be determined in the same way. The type
classification of the frequency inverter contains the device type, the nominal output, data on mains voltage, the
noise suppression filter, protection class and any special device designs.
NOTE
The nomenclature must always be provided in orders and for service and support cases!
