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 connec- tions (including spacings) shall be determined in the end-use application. 7 - Any surface of polymeric housing have not been evaluated as insulating barrier. 8 - 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 ULs Follow-Up Service. Always look for the Mark on the product.
