UL 508: Ratings and assumptions of certification File E189713 Volume: 2 Section: 9 Standards USR indicates investigation to the Standard for Industrial Control Equipment UL 508. CNR indicates investigation to the Canadian standard for Industrial Control Equipment CSA C22.2 No. 14-13 Conditions of acceptability When installed in the end-use equipment, with primary feedthrough potential involved of 600 V AC/DC, consideration shall be given to the following: 1 - These products must be mounted in a suitable end-use enclosure. 2 - The secondary pin terminals have not been evaluated for field wiring. 3 - Low voltage control circuit shall be supplied by an isolating source (such as transformer, optical isolator, limiting impedance or electro-mechanical relay). 4 - Based on the temperature test performed on all Series, the primary bar or conductor shall not exceed 100 C in the end use application. Marking Only those products bearing the UL or UR Mark should be considered to be Listed or Recognized and covered under ULs Follow- Up Service. Always look for the Mark on the product.
