instructions.  
Hot Surface This icon denotes that the component may be  
hot. Touching this component may result in bodily injury.  
Safety Guidelines for Hazardous Voltages  
If hazardous voltages are connected to the module, take the  
following precautions. A hazardous voltage is a voltage greater  
than 42.4 Vpk or 60 VDC to earth ground.  
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 Make sure that devices and circuits connected to  
the module are properly insulated from human contact.

NI 9264 Operating Instructions and Specifications  
 
Caution When module terminals are hazardous voltage  
LIVE (>42.4 Vpk/60 VDC), 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 to ensure that the terminals are not accessible.  
Figure 1 shows the NI 9940 connector backshell.

Safety Guidelines for Hazardous Locations  
The NI 9264 is suitable for use in Class I, Division 2, Groups A, B,  
C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4, and  
NI 9264 Operating Instructions and Specifications

Ex nA IIC T4 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 off or the area is known  
to be nonhazardous.  
Caution Do not remove modules unless power has been  
switched off or the area is known to be nonhazardous.  
Caution Substitution of components may impair  
suitability for Class I, Division 2.  
Caution For Zone 2 applications, install the system  
in an enclosure rated to at least IP 54 as defined by  
IEC 60529 and EN 60529.  
Caution For Zone 2 applications, connected signals must  
be within the following limit:  
Capacitance..........................0.2 μF max

NI 9264 Operating Instructions and Specifications  
 
Special Conditions for Hazardous Locations Use in Europe  
This equipment has been evaluated as Ex nA IIC T4 equipment  
under DEMKO Certificate No. 07 ATEX 0626664X. Each module  
is marked  
II 3G and is suitable for use in Zone 2 hazardous  
locations. If you are using the NI 9264 in Gas Group IIC hazardous  
locations or in ambient temperatures of –40 °C Ta 70 °C, you  
must use the device in an NI chassis that has been evaluated as  
EEx nC IIC T4, Ex nA IIC T4, or Ex nL IIC T4 equipment.  
Special Conditions for Marine Applications  
Some modules are Lloyd’s Register (LR) Type Approved for  
marine applications. To verify Lloyd’s Register certification, visit  
ni.com/certification and search for the LR certificate, or  
look for the Lloyd’s Register mark on the module.  
Caution To meet radio frequency emission requirements  
for marine applications, use shielded cables and install  
the system in a metal enclosure. Suppression ferrites  
must be installed on power supply inputs near power  
entries to modules and controllers. Power supply and  
module cables must be separated on opposite sides of the  
enclosure and must enter and exit through opposing  
enclosure walls.

NI 9264 Operating Instructions and Specifications  
 
Each channel of the NI 9264 has a terminal to which you can  
connect the positive lead of a load. Each channel also has a  
common terminal, COM, and there are four additional COM  
terminals at the bottom of the connector. All of the COM terminals  
are internally connected to the isolated ground reference of the  
module. When connecting a load to the NI 9264, connect the  
positive lead of the load to the AO terminal, and the ground of the  
load to a COM terminal. Refer to Figure 3 for an illustration of  
connecting a load to the NI 9264.

Each channel has a digital-to-analog converter (DAC) that  
produces a voltage signal. Each channel also has overvoltage  
and short-circuit protection. Refer to the Specifications section

Connecting Wires to the NI 9264 Connector  
Use a flathead screwdriver with a blade smaller than 2.3 × 1.0 mm  
(0.09 × 0.04 in.) to connect wires to the detachable spring-terminal  
connector. Insert the screwdriver into a spring clamp activation  
slot and press a wire into the corresponding connector terminal,  
then remove the screwdriver to clamp the wire into the terminal.  
Refer to the Specifications section for more information about  
spring-terminal wiring. Refer to Figure 5 for an illustration of  
connecting wires to the NI 9264.

Wiring for High-Vibration Applications  
If an application is subject to high vibration, National Instruments  
recommends that you use the NI 9940 backshell kit to protect the  
connections. Refer to Figure 1 for an illustration of the NI 9940  
connector backshell.  
Sleep Mode  
This module supports a low-power sleep mode. Support for sleep  
mode at the system level depends on the chassis that the module is  
plugged into. Refer to the chassis manual for information about  
support for sleep mode. If the chassis supports sleep mode, refer to  
the software help for information about enabling sleep mode. Visit  
ni.com/info and enter cseriesdoc for information about  
C Series documentation.  
Typically, when a system is in sleep mode, you cannot  
communicate with the modules. In sleep mode, the system  
consumes minimal power and may dissipate less heat than it does  
in normal mode. Refer to the Specifications section for more  
information about power consumption and thermal dissipation.
