Conditions of acceptability
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.
5 - Primary terminals shall not be straightened since assembly of housing case depends upon bending of the terminals.
6 - Any surface of polymeric housing have not been evaluated as insulating barrier.
7 - Low voltage control circuit shall be supplied by an isolating source (such as a transformer, optical isolator,
limiting impedance or electro-mechanical relay).
Marking
Only those products bearing the 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.
