GETTING STARTED GUIDE

NI 9264

16 AO, ±10 V, 16 Bit, 25 kS/s/ch Simultaneous

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, complete the software 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

Operate the NI 9264 only as described in this document.

Caution Do not operate the NI 9264 in a manner not

specified in this document. Product misuse can result in
a hazard. You can compromise the safety protection
built into the product if the product is damaged in any

2 | ni.com | NI 9264 Getting Started Guide

way. If the product is damaged, return it to NI for
repair.

Hazardous Voltage This icon denotes a warning

advising you to take precautions to avoid electrical
shock.

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.

If hazardous voltages are connected to the device, take the
following precautions. A hazardous voltage is a voltage greater
than 42.4 Vpk voltage 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 Ensure that devices and circuits connected to

the module are properly insulated from human contact.

NI 9264 Getting Started Guide | © National Instruments | 3

Note 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 with the
NI 9264 with spring terminal to ensure that the
terminals are not accessible.

Measurement Category II is for measurements performed on
circuits directly connected to the electrical distribution system.
This category refers to local-level electrical distribution, such as
that provided by a standard wall outlet, for example, 115 V for
U.S. or 230 V for Europe.

Caution Do not connect the NI 9264 to signals or use

for measurements within Measurement Categories III
or IV.

Measurement Category I

Withstand 1,000 Vrms, verified by a 5 s

dielectric withstand test

Measurement Category I is for measurements performed on
circuits not directly connected to the electrical distribution system
referred to as MAINS voltage. MAINS is a hazardous live
electrical supply system that powers equipment. This category is
for measurements of voltages from specially protected secondary
circuits. Such voltage measurements include signal levels, special
equipment, limited-energy parts of equipment, circuits powered
by regulated low-voltage sources, and electronics.

NI 9264 Getting Started Guide | © National Instruments | 5

Caution Do not connect the NI 9264 to signals or use

for measurements within Measurement Categories II,
III, or IV.

Note Measurement Categories CAT I and CAT O are

equivalent. These test and measurement circuits are not
intended for direct connection to the MAINS building
installations of Measurement Categories CAT II,
CAT III, or CAT IV.

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 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.

6 | ni.com | NI 9264 Getting Started Guide

Caution Do not remove modules unless power has

been switched off or the area is known to be
