The National Electrical Manufacturers Association, (NEMA), Rosslyn, Va., recently released two new standards: ICS 7-2000, Adjustable-Speed Drives, and ICS 7.1-2000, Safety Standards for Construction and Guide for Selection, Installation, and Operation of Adjustable-Speed Drive Systems.
Incorporating parts of the document IEC 61800-2-1998, NEMA ICS 7-2000 covers the requirements for adjustable-speed drive systems, including ratings, construction, testing, performance, and manufacturing.
NEMA ICS 7.1-2000 supplements ICS 7 and provides recommendations for the selection, installation, and operation of adjustable-speed drive systems. It is intended to assist electrical manufacturers in designing and building equipment with features that will reduce hazards.
You can purchase NEMA ICS 7-2000 for $67.00 and NEMA ICS 7.1-2000 for $46.00 by calling Global Engineering Documents at (800) 854-7179 (within the U.S.); (303) 397-7956 (international); (303) 397-2740 (fax); or on the Internet at www.global.ihs.com.
