General These requirements cover equipment having ac voltage ratings above 1500 V@ up to 15 kV@ that incorporates switching elements intended for making and breaking the stator circuit of wind turbines investigated to the Standard for Safety for Wind Turbines Permitting Entry of Personnel@ UL 6141. The requirements do not cover variable speed motor controllers (power conversion equipment). These requirements cover equipment intended for use in ordinary locations in accordance with the National Electrical Code. These requirements do not cover equipment intended for starting@ stopping@ regulating@ controlling or protecting electric motors or other electrical loads including refrigeration equipment. Such equipment is covered by the requirements the Standard for Medium-Voltage AC Contactors@ Controllers@ and Control Centers@ UL 347. These requirements are not intended to replace the requirements of IEEE 1547.1@ Standard Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems. When this equipment is used as part of an interconnected system@ it is anticipated that the entire system will be investigated to the requirements of IEEE 1547.1 as appropriate.
