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 not exceeding 1 000 V a.c. or 1 500 V d.c. This document may 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); low voltage stabilized d.c. power supplies. For PECS for which no product standard exists@ this standard provides minimum requirements for safety aspects. This part of IEC 62477 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 International Standard: 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. This International Standard does not cover: telecommunications apparatus other than power supplies to such apparatus; functional safety aspects as covered by e.g. IEC 61508; electrical equipment and systems for railways applications and electric vehicles.
