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.
