Introduction

Table 1- 6: Certifications and Compliances (cont.)

FCC Compliance	Emissions comply with FCC Code of Federal Regulations 47, Part 15, Subpart B, Class A Limits
Installation (Overvoltage)	Terminals on this product may have different installation (overvoltage) category designations. The
Category	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 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 3		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 4		Pollution that generates persistent conductivity through conductive
			dust, rain, or snow. Typical outdoor locations.
Safety Standards
U.S. Nationally Recognized	UL1244		Standard for electrical and electronic measuring and test equipment.
Testing Laboratory Listing
Canadian Certification	CAN/CSA C22.2 No. 231		CSA safety requirements for electrical and electronic measuring and
			test equipment.
European Union Compliance	Low Voltage Directive 73/23/EEC, amended by 93/69/EEC
	EN 61010-1		Safety requirements for electrical equipment for measurement,
			control, and laboratory use.
Additional Compliance	IEC61010-1		Safety requirements for electrical equipment for measurement,
			control, and laboratory use.
