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

Scope

IEC 61800-5-1:2022 specifies requirements for adjustable speed electrical <em>power drive systems (PDS)</em> or their elements, with respect to electrical, thermal, fire, mechanical, energy and other relevant hazards. It does not cover the driven<em> </em>equipment except for interface requirements. It applies to adjustable speed electrical <em>PDS</em> which include the power conversion, <em>basic drive module</em> <em>(BDM)/complete drive module (CDM)</em> control, and a motor or motors.

Excluded are traction and electric vehicle <em>BDM/CDM</em>.

It applies to low-voltage adjustable speed electrical <em>PDS</em> intended to feed a motor or motors from a <em>BDM/CDM</em> 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 <em>PDS</em> intended to feed a motor or motors from a <em>BDM/CDM</em> 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 <em>PDS</em> 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:
