NI-9206 Getting Started

Overview
This document explains how to connect to the NI 9206.
Note Before you begin, complete the soware 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.

NI-9206 Getting Started

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 voltage[1]
AI, PFI0, and D0 to COM ±30 V DC
1 The maximum voltage that can be applied or output between AI and COM without
creating a safety hazard.
Isolation Voltages
Channel-to-channel None
Channel-to-earth ground
Continuous
U.S. (UL 61010-1) 600 V DC, Measurement Category I
Europe (IEC 61010-1) 400 V DC, Measurement Category I
Withstand 2,500 V PK, 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.
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 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 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.
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 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.
Electromagnetic Compatibility Guidelines
