Stresses above these ratings may cause permanent damage. Exposure to absolute maximum ratings for extended periods may
degrade reliability.

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 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 UL’s
Follow-Up Service. Always look for the Mark on the product.
