In the article, “Don’t let power sags stop your motors” ( PE , September 1999, p 76, File 0550/8550), two of the illustrations require further clarification. In Fig. 6., there should be a normally open contact between the overload relay and stop button labeled “undervoltage relay.” In Fig. 7., the relay labeled UV should be normally closed. The author’s telephone number was incorrectly listed. The correct number for Conrad St. Pierre is 518-356-9665.
