to ±10 V, 16 Bit, 250 kS/s Aggregate, Fuel-Cell
Measurements
This document explains how to connect to the NI 9206.
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 9206. 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 9206 only as described in this document.
Caution This icon denotes a caution, which advises
you to consult documentation where this symbol is
marked.
Caution Do not operate the NI 9206 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
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 with the NI 9206.
Safety Voltages
Connect only voltages that are within the following limits:
Maximum voltage1
AI, PFI0, and D0 to
COM
±30 V DC
Isolation Voltages
Channel-to-channel None
1The maximum voltage that can be applied or output between AI and COM
without creating a safety hazard.

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.
Caution Do not connect the NI 9206 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 for
other circuits not intended for direct connection to the
MAINS building installations of Measurement
Categories CAT II, CAT III, or CAT IV.
Safety Guidelines for Hazardous Voltages
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.
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 9941 backshell kit to ensure that the terminals
are not accessible.
Caution In addition to attaching the connector
backshell to the NI 9206, you must install the entire
system in a UL Listed, suitably rated NEMA or IP
enclosure for safe use.

Safety Guidelines for Hazardous Locations
The NI 9206 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
Gc and Ex nA IIC T4 Gc hazardous locations; and nonhazardous
NI 9206 Getting Started Guide | © National Instruments | 7
locations only. Follow these guidelines if you are installing the
NI 9206 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, 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.
Special Conditions for Hazardous Locations Use
in Europe and Internationally
The NI 9206 has been evaluated as Ex nA IIC T4 Gc equipment
under DEMKO 03 ATEX 0324020X and is IECEx UL 14.0089X
8| ni.com | NI 9206 Getting Started Guide
certified. Each NI 9206 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 9206 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.
