Earth-moving machinery - Electrical safety of machines utilizing electric drives and related components and systems - Part 3: Particular requirements for self-powered machines
|Publication Date:||1 November 2016|
|ICS Code (Earth-moving machinery):||53.100|
This document specifies the particular safety requirements for the electrical equipment and its components incorporated in self-powered (utilizing on-board electric power sources) electricallydriven 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.
