DIN EN 62477-1:2013-04

This part of the International Standard series 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. It includes the following content: - This standard specifies a common terminology for safety aspects relating to PECS; - it specifies minimum requirements for the coordination of safety aspects of interrelated parts within a PECS; - this International Standard creates a common basis for minimum safety requirements for the PEC portion of products that contain PEC; - it 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; - it 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 standard may also be used as a reference standard for product committees producing product standards for the following products: - 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 International Standard 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. The responsible committee is DKE/K 331 "Leistungselektronik" ("Power electronics") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
