IEC 61800-5-1 specifies requirements for adjustable speed electrical power drive systems (PDS) or their elements, concerning 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 includes 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.
IEC 61800-5-1 also applies to PDS which intentionally emits or receives radio waves for radio communication.
This edition includes the following significant technical changes:
— harmonization with IEC 62477-1:2022,
— harmonization with UL 61800-5-1 and CSA C22.2 No. 274, including an annex with a list of national deviations which was considered not possible to harmonize within a reasonable timeframe,
— more detailed information about the evaluation of components according to this document and relevant safety component standards,
— an updated requirement for mechanical hazards including multiple IP ratings.
The text of IEC 61800-5-1:2022 has been approved in Europe as EN IEC 61800-5-1:2023 without any changes.
