IEC 60092-501:2013(E) specifies requirements for all electric propulsion plants and gives the specifications, system design, installation and testing of at least:

- generators and their prime movers;

- switchboards;

- transformers/reactors;

- semiconductor convertors;

- propulsion motors;

- excitation systems;

- control, monitoring and safety systems;

- wires, cables, busbars, trunking systems;

- harmonic filters.

Bow and stern thrusters intended as auxiliary steering devices, booster and take-home devices, all auxiliary generating plants, and accumulator battery powered propulsion machinery and equipment are excluded. This fifth edition cancels and replaces the fourth edition published in 2007. It constitutes a technical revision. This edition included the following significant technical changes with respect to the previous edition:

a) requirements regarding system responsibility, electromagnetic compatibility (EMC), harmonic distortion and filtering, special requirements for ships with propulsion motor(s) and podded drives, and power management system (PMS);

b) overall technical review to update the standard according to general requirements and referenced equipme
