CAN/CSA C22.2 No. 1010.1
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.
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.

CSA8000 & TDS8000 Instruments and Sampling Modules
Standard for electrical measuring and test equipment.
Safety requirements for electrical equipment for measurement,
control, and laboratory use.
No pollution or only dry, nonconductive pollution occurs. Products in
this category are generally encapsulated, hermetically sealed, or
located in clean rooms.
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.
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 that generates persistent conductivity through conductive
dust, rain, or snow. Typical outdoor locations.
