inside a product is considered to be the same as the external. Products should be used on ly in the environment for which they

encapsulated, hermetically sealed, or located in clean rooms.
Polution Degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary c onductivity that is caused by
condensation must be expected. This location is a typical office/home enviro nment. Temporary condensation occurs only
when the product is out of service.
