  • an explanation of the assembly characteristics and options within the IEC 61439 series;
  • a guidance on how to select the appropriate options and define characteristics so as to meet specific application needs; and
  • an assistance in the specification of assemblies.
References within this document to the interface characteristics of an assembly and the requirements with which they will comply assume that the assembly is designed, manufactured, and verified in accordance with the relevant part of the IEC 61439 series.
