www.tmeic.comThe nominal ratings are based on 40° C maximum ambient temperature and altitudes less than 1OOOm. Applications outside these conditions require de-rating. b. There are no limitations on input voltage because the input transformer is separate from the drive. The maximum motor voltage is inherent in the converter design depending on the
