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, when necessary we use notes to make you aware of safety
considerations.

Environment and Enclosure

ControlLogix EtherNet/IP Bridge Module 3

ATTENTION

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.

NOTE: 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 the Allen-Bradley
publication 1770-4.1 ("Industrial Automation Wiring and Grounding Guidelines"), for
additional installation requirements pertaining to this equipment.

Prevent Electrostatic Discharge

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.

• If available, use a static-safe workstation.

• When not in use, store the equipment in appropriate

static-safe packaging.

Removal and Insertion Under Power

WARNING

When 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.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.

European Hazardous Location Approval

If you install the module in a European Zone 2 location, consider:

European Zone 2 Certification (The following applies when the product bears the
EEx Marking)

This equipment is intended for use in potentially explosive atmospheres as defined by
European Union Directive 94/9/EC.
The LCIE (Laboratoire Central des Industries Electriques) certifies that this equipment has
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 potentially explosive
atmospheres, given in Annex II to this Directive. The examination and test results are
recorded in confidential report No. 28 682 010.
Compliance with the Essential Health and Safety Requirements has been assured by
compliance with EN 50021.

IMPORTANT

When using this product, also consider the following:

• This equipment is not resistant to sunlight or other sources of UV
radiation.

• The secondary of a current transformer shall not be
open-circuited when applied in Class I, Zone 2 environments.

• Equipment of lesser Enclosure Type Rating must be installed in
an enclosure providing at least IP54 protection when applied in
Class I, Zone 2 environments.

• This equipment shall be used within its specified ratings defined
by Allen-Bradley.

• Provision shall be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 40% when
applied in Class I, Zone 2 environments.

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.
