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.
Overvoltage Category Overvoltage Category II (as defined in IEC 61010-1)
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 1
No pollution or only dry, nonconductive pollution occurs. Products in this
category are generally encapsulated, hermetically sealed, or located in
clean rooms.
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.
Pollution Degree 2 Conductive pollution, or dry, nonconductive pollution that becomes
conductive due to condensation. These are sheltered locations where
neither temperature nor humidity is controlled. The area is protected from
direct sunshine, rain, or direct wind.
Pollution Degree Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.
