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-9269 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

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 NI 9971 connector backshell kit to ensure that

the terminals are not accessible.

and nonhazardous locations only. Follow these guidelines if you are installing the

NI-9269 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.
