BS ISO 14990-2:2016 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.
