This document specifies required measures applicable to the HPI AC Interface between a supply system (typically located on an agricultural tractor) and detachable electrical consumer system (typically located on an agricultural implement).

This document covers the following:

—     HPI system topologies;

—     interface relevant characteristics of the HPI providing AC or combined AC and DC;

—     interface relevant characteristics of the HPI AC load (for relevant characteristics of a DC load, see ISO 23316？5);

—     logical, operational and electrical characteristics of the HPI:

—     operating mode aspects, and

—     communication parameters

NOTE            This document contains simplified electrical diagrams showing specific aspects of the required functionality.
