National Instruments Fieldbus Compliance

Compliance

The Federal Communications Commission (FCC) has rules to protect wireless communications from interference. The FCC

places digital electronics into two classes. These classes are known as Class A (for use in industrial-commercial locations only)

or Class B (for use in residential or commercial locations). All National Instruments (NI) products are FCC Class A products.

Depending on where it is operated, this Class A product could be subject to restrictions in the FCC rules. (In Canada, the

Department of Communications (DOC), of Industry Canada, regulates wireless interference in much the same way.) Digital

electronics emit weak signals during normal operation that can affect radio, television, or other wireless products.

All Class A products display a simple warning statement of one paragraph in length regarding interference and undesired

operation. The FCC rules have restrictions regarding the locations where FCC Class A products can be operated.

Consult the FCC Web site at www.fcc.gov for more information.

This equipment generates and uses radio frequency energy and, if not installed and used in strict accordance with the instructions

in this manual and the CE marking Declaration of Conformity*, may cause interference to radio and television reception.

Classification requirements are the same for the Federal Communications Commission (FCC) and the Canadian Department of

Communications (DOC).

Changes or modifications not expressly approved by NI could void the user’s authority to operate the equipment under the FCC

Rules.

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC

Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated

in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and

used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this

equipment in a residential area is likely to cause harmful interference in which case the user is required to correct the interference

at their own expense.

This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.

Cet appareil numérique de la classe A respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.

Readers in the European Union (EU) must refer to the manufacturer’s Declaration of Conformity (DoC) for information*

pertaining to the CE marking compliance scheme. The manufacturer includes a DoC for most hardware products except for those

bought from OEMs. In addition, DoCs are usually not provided if compliance is not required, for example electrically benign

apparatus or cables.

To obtain the DoC for this product, click Declarations of Conformity Information at ni.com/hardref.nsf/. This Web site

lists the DoCs by product family. Select the appropriate product family, followed by your product, and a link to the DoC appears

in Adobe Acrobat format. Click the Acrobat icon to download or read the DoC.

* The CE marking Declaration of Conformity contains important supplementary information and instructions for the user or

installer.
