Installation (Overvoltage) Category
Terminals on this product may have different installation (overvoltage) category designations.
The installation categories are:
CAT III
Distribution-level mains (usually permanently connected). Equipment at this level is
typically in a fixed industrial location.
CAT II
Local-level mains (wall sockets). Equipment at this level includes appliances, portable
tools, and similar products. Equipment is usually cord-connected.
CAT I
Secondary (signal level) or battery operated circuits of electronic equipment.
Pollution Degree
A measure of the contaminates that could occur in the environment around and within a
product. Typically the internal environment inside a product is considered to be the same as the
external. Products should be used only in the environment for which they are rated.
Pollution Degree 2
Normally only dry, nonconductive pollution occurs. Occasionally a
temporary conductivity that is caused by condensation must be
expected. This location is a typical office/home environment.
Temporary condensation occurs only when the product is out of
service.
