Overview
This document explains how to connect to the NI-9264. In this document, the
NI-9264 with spring terminal and the NI-9264 with DSUB are referred to inclusively
as the NI-9264.
Note Before you begin, read the NI-9264 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-9264. 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
You can connect hazardous voltages only to the NI-9264 with spring terminal. Do not
connect hazardous voltages to the NI-9264 with DSUB.

NI-9264 Getting Started

Caution Ensure that hazardous voltage wiring is performed only by
qualified personnel adhering to local electrical standards.
Caution Do not mix hazardous voltage circuits and human-accessible
circuits on the same module.
Caution Ensure that devices and circuits connected to the module are
properly insulated from human contact.
Note When module terminals are hazardous voltage LIVE (>42.4 Vpk/
60 V DC), you must ensure that devices and circuits connected to the
module are properly insulated from human contact. You must use the
NI-9940 connector backshell kit with the NI-9264 with spring terminal to
ensure that the terminals are not accessible.

Safety Guidelines for Hazardous Locations
The NI-9264 is suitable for use in hazardous locations; , and hazardous locations;
and nonhazardous locations only. Follow these guidelines if you are installing the
NI-9264 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.
Caution For Division 2 and Zone 2 applications, connected signals must
be within the following limits.

Special Conditions for Hazardous Locations Use in Europe and
Internationally
The NI-9264 has been evaluated as equipment under DEMKO ATEX and is IECEx
certified. Each NI-9264 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-9264
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.

Connecting to a Spring-Terminal Connector
What to Use
■ NI-9264 spring-terminal connector
■ copper conductor wire with of insulation stripped from the end
■Flathead screwdriver with a 2.3 mm x 1.0 mm (0.09 in. x 0.04 in.) blade,
included with the NI-9264
What to Do
Complete the following steps to connect wires to the spring-terminal connector.
1. Insert the screwdriver into a spring clamp activation slot to open the
corresponding connector terminal.
2. Press a wire into the open connector terminal.
3. Remove the screwdriver from the activation slot to clamp the wire into place.
High-Vibration Application Connections
If your application is subject to high vibration, NI recommends that you use the
backshell kit to protect connections to the NI-9264 with spring terminal.
Overvoltage Protection
The NI-9264 provides overvoltage protection for each channel.
Note Refer to the NI-9264 Specifications on ni.com/manuals for more
information about overvoltage protection.
