Overview

This document explains how to connect to the NI-9219.

Note Before you begin, read the NI-9219 Safety, Environmental, and

Regulatory Information document on ni.com/manuals and complete the

soware 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

NI-9219 Getting Started

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 eectué 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

NI-9219 Getting Started

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.

Preparing the Environment

Ensure that the environment in which you are using the NI-9219 meets the following

specifications.

Operating temperature (IEC 60068-2-1, IEC 60068-2-2) -40 °C to 70 °C

Operating humidity (IEC 60068-2-78) 10% RH to 90% RH, noncondensing

Pollution Degree 2

Maximum altitude 2,000 m
