Corrigendum 1 - Adjustable speed electrical power drive systems - Part 5-1: Safety requirements - Electrical, thermal and energy

IEC 61800-5-1:2022 specifies requirements for adjustable speed electrical power drive systems (PDS) or their elements, with respect to electrical, thermal, fire, mechanical, energy and other relevant hazards. It does not cover the driven equipment except for interface requirements. It applies to adjustable speed electrical PDS which include the power conversion, basic drive module (BDM)/complete drive module (CDM) control, and a motor or motors.
Excluded are traction and electric vehicle BDM/CDM.
It applies to low-voltage adjustable speed electrical PDS intended to feed a motor or motors from a BDM/CDM connected to phase-to-phase voltages of up to and including 1,0 kV AC (50 Hz or 60 Hz) and up to and including 1,5 kV DC. It also applies to high-voltage adjustable speed electrical PDS intended to feed a motor or motors from a BDM/CDM connected to phase-to-phase voltages of up to and including 35 kV AC (50 Hz or 60 Hz) and up to and including 52 kV DC.
This document also applies to PDS which intentionally emits or receives radio waves for the purpose of radio communication.
This edition includes the following significant technical changes with respect to the previous edition:
a) harmonization with IEC 62477-1:2022;
b) harmonization with UL 61800-5-1 and CSA C22.2 No. 274, including an annex with a list of national deviation which was considered not possible to harmonize within a reasonable timeframe;

semiconductor devices, fuses, circuit breakers, capacitors, overcurrent detection, input inductances and
output inductances) and circuit topologies as the PDS under consideration.
