DIN EN 62109-1:2011-04

Part 1 specifies the safety requirements that are generally applicable to all equipment within the scope of this standard. For certain types of equipment, these requirements will be supplemented or modified by the special requirements of one or more subsequent parts (for example, IEC 62109-2, IEC 62109-3, etcetera) of the standard which must be read in conjunction with the Part 1 requirements. This International Standard applies to power converters for use in photovoltaic (PV) systems where a uniform technical level with respect to safety is necessary. This standard defines the minimum requirements for the design and manufacture of power converters for protection against electric shock, energy, fire, mechanical and other hazards. This standard contains general requirements applicable to all types of PV power converters. There are additional parts of this standard that provide specific requirements for the different types of power converters, such as Part 2 "Inverters". Additional parts may be published as new products and technologies are commercialized. Equipment included in scope: This standard covers power converters connected to systems not exceeding maximum PV source circuit voltage of 1 500 V d.c. This equipment may also be connected to systems not exceeding 1 000 V a.c. at the a.c. mains circuits, non-mains a.c. load circuits, and to other DC source or load circuits such as batteries. This standard may be also used for accessories for use with power converters, except where more appropriate standards exist. Evaluation of power converters to this standard includes evaluation of all features and functions incorporated in or available for the power converters or referred to in the documentation provided with the power converters, if such features or functions can affect compliance with the requirements of this standard. Equipment for which other requirements may apply: This standard is not applicable for characteristics of other sources, such as wind turbines, other rotating machine sources, etcetera. Additional and other requirements are necessary for equipment intended for use in explosive atmospheres (see IEC 60079 "Explosive atmospheres"), aircraft, marine installations, electromedical applications (see IEC 60601 "Medical electrical equipment") or at elevations above 2 000 m. The responsible Committee is 373 "Photovoltaische Solarenergie-Systeme" ("Photovoltaic solar energy systems") of the DKE (German Commission for Electrical, Electronic and Informational Technologies) at DIN and VDE.
