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.
Caution When module terminals are hazardous voltage
LIVE (>42.4 Vpk/60 VDC), youmust ensure that devices
and circuits connected to the module are properly
insulated from human contact. Youmust use the NI 9932
connector backshell kit to ensure that the terminals are
not accessible.

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.
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, in ambient temperatures of –40 °C ≤Ta ≤70 °C. If you
are using the NI 9263 in Gas Group IIC hazardous locations, you
must use the device in an NI chassis that has been evaluated as
Ex nC IIC T4, 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.

Each channel of the NI 9263 has an AO terminal to which youcan
connect the positive lead of a load. Each channel also has a
common terminal, COM, and there is an additional COM terminal
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 9263, connect the
positive lead of the load to the AO terminal, and the ground of the
load to the corresponding COM terminal. Refer to Figure 3 for an
illustration of connecting a load to the NI 9263.
Figure 3. Connecting a Load to the NI 9263
Note Youmust use 2-wire ferrules to create a secure
connection when connecting more than one wire to a
single terminal on the NI 9263.

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
for more information about the overvoltage and short-circuit
protection. Refer to Figure 4 for an illustration of the output
circuitry for one channel of the NI 9263.
Figure 4. Output Circuitry for One Channel of the NI 9263
When the module powers on, the channels output the startup
voltage. Refer to the Specifications section for more information
about startup voltage. Refer to the software help for information
about configuring startup output states in software.

Wiring for High-Vibration Applications
If an application is subject to high vibration, National Instruments
recommends that youeither use ferrules to terminate wires to the
detachable screw-terminal connector or use the NI 9932 backshell
kit to protect the connections. Refer to Figure 5 for an illustration
of using ferrules. Refer to Figure 1 for an illustration of the
NI 9932 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, youcannot
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.
