Hazardous Voltage This icon denotes a warningadvising you to take precautions to avoid electricalshock.

Safety Guidelines for Hazardous VoltagesIf hazardous voltages are connected to the device, take thefollowing precautions. A hazardous voltage is a voltage greaterthan 42.4 Vpk voltage or 60 VDC to earth ground.

Caution Ensure that hazardous voltage wiring isperformed only by qualified personnel adhering to localelectrical standards.

Caution Do not mix hazardous voltage circuits andhuman-accessible circuits on the same module.

Caution Ensure that devices and circuits connected tothe module are properly insulated from human contact.

Caution When module terminals are hazardousvoltage LIVE (>42.4 Vpk/60 VDC), you must ensurethat devices and circuits connected to the module areproperly insulated from human contact. You must usethe 6-position connector backshell kit (783804-01)

connector backshell kit to ensure that the terminals arenot accessible.

Safety Guidelines for Hazardous LocationsThe NI 9997 is suitable for use in Class I, Division 2, Groups A,B, C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4and Ex nA IIC T4 hazardous locations; and nonhazardouslocations only. Follow these guidelines if you are installing theNI 9997 in a potentially explosive environment. Not followingthese guidelines may result in serious injury or death.

Caution Do not disconnect I/O-side wires orconnectors unless power has been switched off or thearea is known to be nonhazardous.

Caution Do not remove modules unless power hasbeen switched off or the area is known to benonhazardous.

Caution Substitution of components may impairsuitability for Class I, Division 2.

Caution For Division 2 and Zone 2 applications,install the system in an enclosure rated to at least IP54as defined by IEC/EN 60079-15.


Special Conditions for Hazardous Locations Use inEurope and InternationallyThe NI 9997 has been evaluated as Ex nA IIC T4 Gc equipmentunder DEMKO Certificate No. 12 ATEX 1202658X and isIECEx UL 14.0089X certified. Each NI 9997 is marked II 3Gand is suitable for use in Zone 2 hazardous locations, in ambienttemperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI 9997in Gas Group IIC hazardous locations, you must use the device inan NI chassis that has been evaluated as Ex nC IIC T4, Ex IICT4, Ex nA IIC T4, or Ex nL IIC T4 equipment.

Caution You must make sure that transientdisturbances do not exceed 140% of the rated voltage.

Caution The system shall only be used in an area ofnot more than Pollution Degree 2, as defined inIEC 60664-1.

Caution The system shall be mounted in anATEX/IECEx-certified enclosure with a minimumingress protection rating of at least IP54 as defined inIEC/EN 60079-15.


Caution The enclosure must have a door or coveraccessible only by the use of a tool.

Electromagnetic Compatibility GuidelinesThis product was tested and complies with the regulatoryrequirements and limits for electromagnetic compatibility (EMC)stated in the product specifications. These requirements andlimits provide reasonable protection against harmful interferencewhen the product is operated in the intended operationalelectromagnetic environment.

This product is intended for use in industrial locations. However,harmful interference may occur in some installations, when theproduct is connected to a peripheral device or test object, or if theproduct is used in residential or commercial areas. To minimizeinterference with radio and television reception and preventunacceptable performance degradation, install and use thisproduct in strict accordance with the instructions in the productdocumentation.

Furthermore, any changes or modifications to the product notexpressly approved by National Instruments could void yourauthority to operate it under your local regulatory rules.


Special Conditions for Marine ApplicationsSome products are Lloyd’s Register (LR) Type Approved formarine (shipboard) applications. To verify Lloyd’s Registercertification for a product, visit ni.com/certification and searchfor the LR certificate, or look for the Lloyd’s Register mark onthe product.

Caution In order to meet the EMC requirements formarine applications, install the product in a shieldedenclosure with shielded and/or filtered power andinput/output ports. In addition, take precautions whendesigning, selecting, and installing measurement probesand cables to ensure that the desired EMC performanceis attained.
