UL 508: Ratings and assumptions of certification File E189713 Volume: 2 Section: 5 Standards CSA C22.2 NO. 14-10 INDUSTRIAL CONTROL EQUIPMENT - Edition 11 - Revision Date 2011/08/01 UL 508 STANDARD FOR INDUSTRIAL CONTROL EQUIPMENT - Edition 17 - Revision Date 2010/04/15 Ratings Parameter Symbol Unit Value Primary involved potential V AC/DC 600 Max surrounding air temperature T C 105 A According to series primary Primary current I A P currents Secondary supply voltage U V DC 5 C V Output voltage V 0 to 5 out Conditions of acceptability When installed in the end-use equipment, consideration shall be given to the following: 1 - These devices have been evaluated for overvoltage category III and for use in pollution degree 2 environment. 2 - A suitable enclosure shall be provided in the end-use application. 3 - The terminals have not been evaluated for field wiring. 4 - These devices have been evaluated for use in 105 C maximum surrounding air temperature. 5 - The secondary (Sensing) circuit is intended to be supplied by a Isolated Secondary Circuit - Limited voltage circuit defined by UL 508 paragraph 32.5. The maximum open circuit voltage potential available to the circuit and overcurrent protection shall be evaluated in the end use application. 6 - These devices are intended to be mounted on a printed wiring board of end-use equipment. The suitability of the connections (including spacings) shall be determined in the end-use application. 7 - Primary terminals shall not be straightened since assembly of housing case depends upon bending of the terminals. 8 - Any surface of polymeric housing have not been evaluated as insulating barrier. 9 - Low voltage circuits are intended to be powered by a circuit derived from an isolating source (such as a transformer , optical isolator, limiting impedance or electro-mechanical relay) and having no direct connection back to the primary circuit (other than through the grounding means). Marking Only those products bearing the UL or UR Mark should be considered to be Listed or Recognized and covered under UL s Follow-Up Service. Always look for the Mark on the product.
