Earth-moving machinery — Electrical safety of machines utilizing electric drives and related components and systems — Part 2: Particular requirements for externally-powered machines
Preview
Summary
This document specifies the particular safety requirements for the electrical equipment and its
components incorporated in externally-powered (mains-connected, including machines powered by
external dedicated generators), 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 self-powered machines are given
in ISO 14990-3. However, it is possible for an EMM to be 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 14990-3 is also applicable.
