Overview
This document explains how to connect to the NI 9205.
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 9205. 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 9205 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 9205 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 9205 with spring
terminal .
Safety Voltages
Connect only voltages that are within the following limits:
Maximum voltage[1]
Channel-to-COM ±30 V DC
1 The maximum voltage that can be applied or output between AI and COM without
creating a safety hazard.
NI 9205 with Spring Terminal Isolation Voltages
Channel-to-channel None
Channel-to-earth ground
Continuous 250 V RMS, Measurement Category II
Withstand
up to 2,000 m 3,000 V RMS, verified by a 5 s dielectric withstand test
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 9205 to signals or use for measurements
within Measurement Categories III or IV.

NI 9205 with DSUB Isolation Voltages
Channel-to-channel None
Channel-to-earth ground
Continuous 60 V DC, Measurement Category I
Withstand
up to 2,000 m 1,000 V RMS, verified by a 5 s dielectric withstand test
up to 5,000 m 500 V RMS
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 9205 with DSUB 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.
© National Instruments 5
NI-9205 Getting Started

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 9940 backshell kit to ensure that the terminals are not accessible.
Safety Guidelines for Hazardous Locations
The NI 9205 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 9205 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.

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.
