In the past, motors have either complied with the motor standard UL 1004-1 or complied withthe applicable requirements in UL 1017. The Integral Insul
24、ation requirements are derived from C22.2 No.100-04 (R2009). This reflects present practice regarding the application of these requirements.Copyright 2013 Underwriters Laboratories Inc.STANDARD NUMBER: UL 1017 -3-UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT
