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.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. 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.

WARNING

Identifies information about practices or circumstances that can cause an

explosion in a hazardous environment, which may lead to personal injury or

death, property damage, or economic loss.

IMPORTANT

Identifies information that is critical for successful application and understanding

of the product.

ATTENTION

Identifies information about practices or circumstances that can lead to

personal injury or death, property damage, or economic loss. Attentions

help you:

• identify a hazard

• avoid a hazard

• recognize the consequence

ATTENTION

Environment and Enclosure

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 (6562 ft) 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

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, for

additional installation requirements, Allen-Bradley publication

1770-4.1.

• NEMA Standards publication 250 and IEC publication 60529, as

applicable, for explanations of the degrees of protection provided by

different types of enclosure.

ATTENTION

FLEX I/O 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 (7.8 in.) and use end-anchors appropriately.

ATTENTION

Preventing Electrostatic Discharge

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.

• Store the equipment in appropriate static-safe packaging when not

in use.

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

Do not connect directly to line voltage. Line voltage must be supplied by a

suitable, approved isolating transformer or power supply having short circuit

capacity not exceeding 100 VA maximum or equivalent.

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 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.

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

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

classé non dangereux avant de changer

les piles.
