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://www.ab.com/manuals/gi) 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. cannot assume responsibility or liability for actual use based on the
examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of
information, circuits, equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written permission of
Rockwell Automation, Inc. is prohibited.
Throughout this manual we use notes to make you aware of safety considerations.

North American Hazardous Location Approval
The following modules are North American Hazardous Location approved:
1794-IE8/B, 1794-IE8K/B, 1794-OE4/B, 1794-OE4K/B and 1794-IE4XOE2/B.
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.
