a. Pollution Degree 2 – A measure of pollution on electrical circuits that can produce a reduction of dielectric strength or
surface resistivity. Degree 2 refers only to normally nonconductive pollution. Occasionally, however, expect a temporary
conductivity caused by condensation.
b. Moisture Protection – Normal (IPX0) – IPX0 means that no Ingress Protection against any type of dripping or sprayed water
exists. The "X" is a placeholder that identifies protection against dust, if applicable.
