Scope

This part of IEC 62477 applies to power electronic converter systems (PECS) and equipment@ their components for electronic power conversion and electronic power switching@ including the means for their control@ protection@ monitoring and measurement@ such as with the main purpose of converting electric power@ with rated system voltages from 1 000 V AC or 1 500 V DC up to 36 kV AC or 54 kV DC. This document can also be used as a reference standard for product committees producing product standards for ? adjustable speed electric power drive systems (PDS)@ ? standalone uninterruptible power systems (UPS)@ and ? stabilized DC power supplies. For PECS for which no product standard exists@ this document provides minimum requirements for safety aspects. This document has the status of a group safety publication in accordance with IEC Guide 104 for power electronic converter systems and equipment for solar@ wind@ tidal@ wave@ fuel cell or similar energy sources. According to IEC Guide 104@ one of the responsibilities of technical committees is@ wherever applicable@ to make use of basic safety publications and/or group safety publications in the preparation of their product standards. This document ? establishes a common terminology for safety aspects relating to PECS and equipment@ ? establishes minimum requirements for the coordination of safety aspects of interrelated parts within a PECS@ ? establishes a common basis for minimum safety requirements for the PEC portion of products that contain PEC@ ? specifies requirements to reduce risks of fire@ electric shock@ thermal@ energy and mechanical hazards@ during use and operation and@ where specifically stated@ during service and maintenance@ ? specifies minimum requirements to reduce risks with respect to pluggable and permanently connected equipment@ whether it consists of a system of interconnected units or independent units@ subject to installing@ operating and maintaining the equipment in the manner prescribed by the manufacturer@ ? establishes an arc fault rating label requirement with testing instructions for PEC and PECS@ and ? covers power electronic converters and systems in open type design@ which are catalog (pre-defined commercially available) power electronic converters and systems or engineered solutions from same. This document does not cover ? telecommunications apparatus other than power supplies to such apparatus@ ? functional safety aspects as covered by@ for example@ IEC 61508 (all parts)@ ? electrical equipment and systems for railways applications and electric vehicles@ and ? power electronic converters and systems in open type design@ which are ?C in their major part ?C dimensioned@ designed and constructed according to the user??s individual requirements and specifications and follow power installation standards@ for example IEC 61936-1.
