Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical
equipment Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls
(Publication SGI-1.1 available from your local Rockwell Automation sales office or online at
http://literature.rockwellautomation.com) describes some important differences between solid state
equipment and hard-wired electromechanical devices. Because of this difference, and also because of the
wide variety of uses for solid state equipment, all persons responsible for applying this equipment must
satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the
many variables and requirements associated with any particular installation, Rockwell Automation, Inc.

Environment and Enclosure
Prevent Electrostatic Discharge
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters without derating.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR Publication 11. Without appropriate precautions, there may be
potential difficulties ensuring electromagnetic compatibility in other
environments due to conducted as well as radiated disturbance.
This equipment is supplied as open-type equipment. It must be mounted within
an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The interior of the enclosure
must be accessible only by the use of a tool. Subsequent sections of this
publication may contain additional information regarding specific enclosure
type ratings that are required to comply with certain product safety
certifications.
See NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by different
types of enclosure. Also, see the appropriate sections in this publication, as
well as Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley
publication 1770-IN041, for additional installation requirements pertaining to
this equipment.
ATTENTION: This equipment is sensitive to electrostatic discharge, which can
cause internal damage and affect normal operation. Follow these guidelines
when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.

Publication 1794-IN106D-EN-E - January 2014
WARNING: If you insert or remove the module while backplane power is on,
an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
WARNING: If you connect or disconnect wiring while the field side power is
on, an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
ATTENTION: This product is grounded through the DIN rail to chassis
ground. Use zinc plated yellow-chromate steel DIN rail to assure proper
grounding. The use of other DIN rail materials (such as aluminum or plastic)
that can corrode, oxidize, or are poor conductors, can result in improper or
intermittent grounding.
ATTENTION: To comply with the CE Low Voltage Directive (LVD), all
connections to this equipment must be powered from a source compliant
with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).

The following information applies when
operating this equipment in hazardous
locations:
Informations sur l’utilisation de cet équipement
en environnements dangereux:
Products marked CL I, DIV 2, GP A, B, C, D are suitable for
use in Class I Division 2 Groups A, B, C, D, hazardous
locations and nonhazardous locations only. Each product
is supplied with markings on the rating nameplate
indicating the hazardous location temperature code.
When combining products within a system, the most
adverse temperature code (lowest “T” number) may be
used to help determine the overall temperature code of
the system. Combinations of equipment in your system
are subject to investigation by the local Authority Having
Jurisdiction at the time of installation.
Les produits marqués CL I, DIV 2, GP A, B, C, D ne conviennent
qu’à une utilisation en environnements de Classe I Division 2
Groupes A, B, C, D dangereux et non dangereux. Chaque produit
est livré avec des marquages sur sa plaque d’identification qui
indiquent le code de température pour les environnements
dangereux. Lorsque plusieurs produits sont combinés dans un
système, le code de température le plus défavorable (code de
température le plus faible) peut être utilisé pour déterminer le
code de température global du système. Les combinaisons
d’équipements dans le système sont sujettes à inspection par
les autorités locales qualifiées au moment de l’installation.
WARNING: EXPLOSION
HAZARD
• Do not disconnect equipment

Install Your Analog Input/Output Module
These modules mount on a 1794-TB3G or 1794-TB3GS terminal base.
1. Rotate the keyswitch (1) on the terminal base (2) clockwise to position 3
(1794-IE12), 4 (1794-OE12), or 5 (1794-IE8XOE4) as required.
2. Make certain the FLEXBus connector (3) is pushed all the way to the left to
connect with the neighboring terminal base/adapter. You cannot install the
module unless the connector is fully extended.
3. Make sure the pins on the bottom of the module are straight so they will align
properly with the connector in the terminal base.
4. Position the module (4) with its alignment bar (5) aligned with the groove (6) on
the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit. The module
is seated when the latching mechanism (7) is locked into the module.
