Summary

This document specifies the particular safety requirements for the electrical equipment and its
components incorporated in self-powered (utilizing on-board electric power sources) electrically-
driven earth-moving machines (EMMs).
It is applicable to those machines using on-board voltages in the range of 50 V–36 kV AC r.m.s. at any
frequency, and 75 V–36 kV DC — including any repetition rate of pulsating DC— intended for outdoor use.
Voltages occurring within devices are not considered to be on-board voltages and are thus not within
its scope.
It is intended to be used in conjunction with ISO 14990-1, which gives general requirements for EMMs
regardless of how they are powered. Requirements specific to externally-powered machines are
given in ISO 14990-2. It is possible to have an EMM that is both self-powered and externally powered
(e.g. a battery powered machine having a built-in charger with power supply function), in which case
ISO 14990-2 is also applicable.
NOTE For machines intended to be operated on-road, automotive standard ISO 6469 and/ or UN ECE R100
may provide useful guidance. See Annex B for a comparison of requirements.
