Safety of power converters for use in photovoltaic power systems - Part 1: General requirements
IEC 62109-1:2010 applies to the power conversion equipment (PCE) for use in photovoltaic systems where a uniform technical level with respect to safety is necessary. Defines the minimum requirements for the design and manufacture of PCE for protection against electric shock, energy, fire, mechanical and other hazards. Provides general requirements applicable to all types of PV PCE.
Sécurité des convertisseurs de puissance utilisés dans les systèmes photovoltaïques - Partie 1: Exigences générales
l'IEC 62109-1:2010 s'applique aux équipements de conversion de puissance (PCE – power conversion equipment en anglais) utilisés dans les systèmes photovoltaïques (PV) nécessitant un niveau technique uniforme en matière de sécurité. La présente norme définit les exigences minimales relatives à la conception et à la fabrication de PCE pour la protection contre les chocs électriques, les risques liés à l'électricité, les incendies, les dangers mécaniques et autres dangers. La présente norme fournit des exigences générales applicables à tous les types d'équipement de conversion de puissance photovoltaïque (PV PCE).
