Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had received notice of
(a) patent(s) which may be required to implement this document. However, implementers are cautioned
that this may not represent the latest information, which may be obtained from the patent database
available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent
rights.

Introduction
The purpose of the ISO 23316 series is to provide design and application standards covering
implementation of electrical high-power interface with a nominal voltage of 700 V DC/480 V AC for
agricultural and forestry machinery.
Conformance to the ISO 23316 series is determined when applicable requirements from all parts of the
ISO 23316 series are met.
It is permitted for partial systems or components to conform with the ISO 23316 series by applying all
applicable requirements, e.g. for the plug, receptacle, or inverters, on a tractor or implement.
NOTE For example, if a DC-mode only HPI is provided, it is not necessary to conform with ISO 23316-4
describing AC-mode, as it is not applicable. If an AC-mode only HPI is provided, it is not necessary to conform with
ISO 23316-5 describing DC-mode, as it is not applicable.
The ISO 23316 series specifies physical and logical interface requirements that provide interoperability
and cross compatibility for systems and equipment operating at nominal voltages of 700 V DC/480 V
AC.
ISO 23316-1 describes the general purpose and structure of standards in the ISO 23316 series.
The structure of safety standards in the field of machinery is as follows:
— type-A standards (basis safety standards) giving basic concepts, principle for design, and general
aspects that can be applied to machinery;
— type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguards
that can be used across a wide range of machinery:
— type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature,
noise);
— type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, pressure
sensitive devices, guards);
— type-C standards (machinery safety standards) dealing with detailed safety requirements for a
particular machine or group of machines.
This document is a type C standard as stated in ISO 12100.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards for machines that have been designed and built according to the provisions of this type C
standard.
The machinery concerned and the extent to which hazards, hazardous situations and events are
covered are indicated in the scope of this document.
