Regulatory Information document on ni.com/manuals and complete the
soware and hardware installation procedures in your chassis
documentation.
Note The guidelines in this document are specific to the NI-9219. The
other components in the system might not meet the same safety ratings.
Refer to the documentation for each component in the system to
determine the safety and EMC ratings for the entire system.
Safety Guidelines
Caution Observe all instructions and cautions in the user documentation.
Using the product in a manner not specified can damage the product and
compromise the built-in safety protection.
Attention Suivez toutes les instructions et respectez toutes les mises
en garde de la documentation d'utilisation. L'utilisation du produit de
toute autre façon que celle spécifiée risque de l'endommager et de
compromettre la protection de sécurité intégrée.
Safety Guidelines for Hazardous Voltages
If hazardous voltages are connected to the product, take the following precautions.
A hazardous voltage is a voltage greater than:
■ 30 V RMS, 42.4 V peak, or 60 V DC in DRY LOCATIONS
■ 16 V RMS, 22.6 V peak, or 35 V DC in WET LOCATIONS

Caution Ensure that hazardous voltage wiring is performed only by
qualified personnel adhering to local electrical standards.
Attention S'assurer que le câblage à tension dangereuse est eectué par
du personnel qualifié respectant les normes électriques locales.
Caution Do not mix hazardous voltage circuits and human-accessible
circuits on the same product.
Attention Ne pas combiner des circuits avec des tensions dangereuses et
des circuits accessibles aux personnes sur le même produit.
Caution When product terminals are hazardous voltage LIVE, you must
ensure that devices and circuits connected to the product are properly
insulated from human contact.
Attention Lorsqu'une haute tension dangereuse est appliquée aux
bornes du produit, vous devez vous assurer que les appareils et les circuits
auxquels il est connecté sont correctement isolés de tout contact humain.
Caution You must use the connector backshell kit to ensure that the
terminals are not accessible.

Safety Guidelines for Hazardous Locations
The NI-9219 is suitable for use in hazardous locations; , and hazardous locations;
and nonhazardous locations only. Follow these guidelines if you are installing the
NI-9219 in a potentially explosive environment. Not following these guidelines may
result in serious injury or death.
Caution Do not disconnect I/O-side wires or connectors unless power has
been switched o or the area is known to be nonhazardous.
Caution Do not remove modules unless power has been switched o or
the area is known to be nonhazardous.
Caution Substitution of components may impair suitability for Class I,
Division 2, or Zone 2.
Caution The system must be installed in an enclosure certified for the
intended hazardous (classified) location, having a tool secured cover/door,
where a minimum protection of at least IP54 is provided.

Special Conditions for Hazardous Locations Use in Europe and
Internationally
The NI-9219 has been evaluated as equipment under DEMKO ATEX and is IECEx
certified. Each NI-9219 is marked and is suitable for use in Zone 2 hazardous
locations, in ambient temperatures of -40 °C ≤ Ta ≤ 70 °C. If you are using the NI-9219
in Gas Group IIC hazardous locations, you must use the device in an NI chassis that
has been evaluated as Ex nC IIC T4, Ex IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.
Caution Transient protection shall be provided that is set at a level not
exceeding 140% of the peak rated voltage value of 85 V at the supply
terminals to the equipment.
Caution The system shall only be used in an area of not more than
Pollution Degree 2, as defined in IEC/EN 60664-1.
Caution The system shall be mounted in an ATEX/IECEx-certified
enclosure with a minimum ingress protection rating of at least IP54 as
defined in IEC/EN 60079-15.
Caution The enclosure must have a door or cover accessible only by the
use of a tool.
Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits
for electromagnetic compatibility (EMC) stated in the product specifications. These
requirements and limits provide reasonable protection against harmful interference
when the product is operated in the intended operational electromagnetic
environment.
This product is intended for use in industrial locations. However, harmful
interference may occur in some installations, when the product is connected to a
peripheral device or test object, or if the product is used in residential or
commercial areas. To minimize interference with radio and television reception and

prevent unacceptable performance degradation, install and use this product in strict
accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved
by National Instruments could void your authority to operate it under your local
regulatory rules.
Special Conditions for Marine Applications
Some products are approved for marine (shipboard) applications. To verify marine
approval certification for a product, visit ni.com/product-certifications, search by
model number, and click the appropriate link.
Notice In order to meet the EMC requirements for marine applications,
install the product in a shielded enclosure with shielded and/or filtered
power and input/output ports. In addition, take precautions when
designing, selecting, and installing measurement probes and cables to
ensure that the desired EMC performance is attained.
