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.
