AS ISO 14990.3:2022 PDF

AS ISO 14990.3:2022 identically adopts ISO 14990 3:2016, which 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 AS 14990.1:2022, which gives general requirements for EMMs regardless of how they are powered. Requirements specific to externally-powered machines are given in AS ISO 14990.2:2022. 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 AS ISO 14990.2:2022 is also applicable.

This document is identical with, and has been reproduced from, ISO 14990-3:2016, Earth-moving machinery — Electrical safety of machines utilizing electric drives and related components and systems — Part 3: Particular requirements for self-powered machines.
