DIN EN 61800-5-2:2017-11

This part of the DIN EN 61800 series of contains requirements and makes recommendations for the design and development, integration and validation of safety related power drive systems. The standard applies to adjustable speed electrical power drive systems covered by the other parts of the series. This part of IEC 61800 sets out safety-related considerations of PDS(SR)s in terms of the framework of IEC 61508, and introduces requirements for PDS(SR)s as subsystems of a safety-related system. It is intended to facilitate the realisation of the electrical/ electronic/ programmable electronic (E/E/PE) parts of a PDS(SR) in relation to the safety performance of safety sub-function(s) of a PDS. Manufacturers and suppliers of PDS(SR)s by using the normative requirements of this part of IEC 61800 will indicate to users (system integrator, original equipment manufacturer) the safety performance for their equipment. This will facilitate the incorporation of a PDS(SR) into a safety-related control system using the principles of IEC 61508, and possibly its specific sector implementations (for example IEC 61511, IEC 61513, IEC 62061 or ISO 13849). By applying the requirements from this part of the IEC 61800 series, the corresponding requirements of IEC 61508 that are necessary for a PDS(SR) are fulfilled. This part of IEC 61800 only applies to PDS(SR)s implementing safety sub-functions with a SIL not greater than SIL 3. The responsible committee is DKE/K 226 "Ausrüstung von Starkstromgeräten und -anlagen mit elektronischen Betriebsmitteln" ("High voltage current equipment and systems with electronic equipment") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
