Standards or description
Compliance was demonstrated to the following specification as listed in the Official Journal of the
European Union:
Low Voltage Directive 73/23/EEC, amended by 93/69/EEC
EN 61010 1:1993
Safety requirements for electrical equipment for measurement control and
laboratory use.
UL3111 1
Standard for electrical measuring and test equipment.
CAN/CSA C22.2 No. 1010.1
Safety requirements for electrical equipment for measurement, control, and
laboratory use.
IEC61010 1
Safety requirements for electrical equipment for measurement, control,
and laboratory use.
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.
Pollution Degree 2
Test and measuring
Class 1 (as defined in IEC 1010 1, Annex H) - grounded product
Overvoltage Category II (as defined in IEC 1010 1, Annex J)
Pollution Degree 2 (as defined in IEC 1010 1). Note: Rated for indoor use only.
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.
