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.

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 only be changed in an
area known to be nonhazardous.

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.

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.

•La substitution de composants peut
rendre cet équipement inadapté à
une utilisation en environnement de
Classe I, Division 2.

•S'assurer que l'environnement est

European Hazardous Location Approval

The following applies when the product bears the Ex Marking.
This equipment is intended for use in potentially explosive atmospheres as

defined by European Union Directive 94/9/EC.
Intertek 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 Zone 2 potentially
explosive atmospheres, given in Annex II to this Directive. The examination and
test results are recorded in confidential report No.100014190DAL-001.

Compliance with the Essential Health and Safety Requirements has been
assured by compliance with EN 60079-15.

WARNING: This equipment must be installed in an enclosure
providing at least IP54 protection when applied in Zone 2
environments.

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

Rockwell Automation Publication 1768-IN002B-EN-P - August 2010

CompactLogix EtherNet/IP Communication Module 5

Environment and Enclosure

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:

• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1
requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by different
types of enclosure.

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.

DIN rail Either of these sizes:

• 35 x 7.5 mm (EN 50 022 - 35 x 7.5)

• 35 x 15 mm (EN 50 022 - 35 x 15)

Screws M4 or #8 panhead screws

Install the Modules

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 (for
example, aluminum or plastic) that can corrode, oxidize, or are
poor conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200 mm
(7.87 in.) and use end-anchors appropriately.

If You Are Using Screws to Mount Your Modules

IMPORTANT

The steps in these instructions show how to mount the modules on DIN rail.
If you are using screws instead of DIN rail, make these changes to the
instructions.

1. Follow the steps in Mount the Controller on the DIN Rail

connect the modules together.

2. Use the modules as a template and mark pilot holes on your panel.

3. Drill the pilot holes for M4 or #8 screws.

4. Use M4 or #8 screws to mount the modules to your panel. Use

1.16 N•m (10 lb•in) of torque.

5. Ground the module on a ground bus with a dedicated earth ground

stake.

6. Connect the ground bus to a functional earth ground on the DIN rail or

panel.

7. Refer to Industrial Automation Wiring and Grounding Guidelines,

publication 1770-4.1

Do not use screws and DIN rail to mount the modules. It is
possible to break the mounting tabs off if you screw the modules
to the panel while they are on DIN rail.
