North American Hazardous Location Approval
The following information applies when operating this equipment in hazardous locations:
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.
Informations sur l'utilisation de cet équipement en environnements dangereux:
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
European Hazardous Location Approval
The following applies to products marked
II 3 G: This equipment:
• is intended for use in potentially explosive atmospheres as defined by European Union Directive 94/9/EC and have been
found to comply with the Essential Health and Safety Requirements relating to the design and construction of Category 3
equipment intended for use in Zone 2 potentially explosive atmospheres, given in Annex II to this Directive. Compliance
with the Essential Health and Safety Requirements has been assured by compliance with EN 60079-15 and EN 60079-0.
See the EC Declaration of Conformity at
http://www.rockwellautomation.com/products/certification
for details. The type
of protection used is “Ex nA IIC T5- Gc“ or “Ex nA IIC T4- Gc” according to EN 60079-15. The specific temperature code is
marked on the product.
• is intended for use in areas in which explosive atmospheres caused by gases, vapors, mists, or air mixtures are unlikely to
occur, or are likely to occur only infrequently and for short periods. Such locations correspond to Zone 2 classification
according to ATEX directive 1999/92/EC.
• complies with standards EN 60079-0:2009 and EN 60079-15:2010, reference certificate number ITS09ATEX46118X, for
only L3xE controllers.

ATTENTION:
• Before installing, configuring, operating, or maintaining this product, read this document and the
documents listed in the Additional Resources section for installing, configuring, or operating equipment.
Users should familiarize themselves with installation and wiring instructions in addition to requirements
of all applicable codes, laws, and standards.
• Installation, adjustments, putting into service, use, assembly, disassembly, and maintenance shall be
carried out by suitably trained personnel in accordance with applicable code of practice. In case of
malfunction or damage, no attempts at repair should be made. The module should be returned to the
manufacturer for repair. Do not dismantle the module.
• If this equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
• For Modular CompactLogix controllers, this equipment is certified for use only within the surrounding air
temperature range of 0…60 °C (32…140 °F). The equipment must not be used outside of this range.
• 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.rockwellautomation.com/literature
, describes some important differences between
solid-state equipment and hard-wired electromechanical devices.
IMPORTANT
Any illustrations, charts, sample programs, and layout examples shown in this publication are
intended solely for the purposes of example. Since there are many variables and requirements
associated with any particular installation, Rockwell Automation does not assume responsibility or
liability for actual use based upon the examples shown in this publication.
ATTENTION:
This equipment is intended for use in a Pollution Degree 2 industrial environment, in
overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft) without
derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11. Without
appropriate precautions, there may be difficulties with electromagnetic compatibility in residential and
other environments due to conducted and radiated disturbances.
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 enclosure must have
suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame
spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic. 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.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, publication
for additional installation
requirements
• NEMA 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided by
different types of enclosure
WARNING:
EXPLOSION HAZARD
• Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous.
• Do not disconnect connections to this equipment unless power has been removed or the area is known to
be nonhazardous. Secure any external connections that mate to this equipment by using screws, sliding
latches, threaded connectors, or other means provided with this product.
• Substitution of components may impair suitability for Class I, Division 2.
• If this product contains batteries, they must be changed only in an area known to be nonhazardous.
AVERTISSEMENT:
RISQUE D'EXPLOSION
• Couper le courant ou s'assurer que l'environnement est classé non dangereux avant de débrancher
l'équipement.
• Couper le courant ou s'assurer que l'environnement est classé non dangereux avant de débrancher les
connecteurs. Fixer tous les connecteurs externes reliés à cet équipement à l'aide de vis, loquets
coulissants, connecteurs filetés ou autres moyens fournis avec ce produit.

WARNING:
Special Conditions for Safe Use:
• This equipment shall be mounted in an ATEX-certified enclosure with a minimum ingress protection
rating of IP54 (as defined in IEC60529) and used in an environment of not more than Pollution Degree 2

• Touch a grounded object to discharge potential static.
• Wear an approved grounding wrist strap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
