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://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, when necessary, 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 and recognize the consequences.

Labels may be on or inside the equipment (for example, a drive or motor) to alert

people that dangerous voltage may be present.

Publication 1756-IN101L-EN-P - June 2008

Explosion Hazards

Preventing Electrostatic Discharge

Removing Module While Under Power (RIUP)

WARNING An electrical arc can occur if you:

xinsert or remove the CompactFlash card.

xinsert or remove the controller while backplane power is on.

xconnect or disconnect the battery.

xconnect or disconnect the serial cable with power applied to this module

or the serial device on the other end of the cable.

This could cause an explosion in hazardous location installations. Make sure

that power is removed or the area is nonhazardous before proceeding

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.

xTouch a grounded object to discharge potential static.

xWear an approved grounding wriststrap.

xDo not touch connectors or pins on component boards.

xDo not touch circuit components inside the equipment.

xUse a static-safe workstation, if available.

xStore the equipment in appropriate static-safe packaging when not in

use.

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.

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

publication 60664-1), at altitudes up to 2000 m (6561 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:

xIndustrial Automation Wiring and Grounding Guidelines, for additional

installation requirements, Allen-Bradley publication 1770-4.1.

xNEMA Standards publication 250 and IEC publication 60529, as

applicable, for explanations of the degrees of protection provided by

different types of enclosure.

North American Hazardous Location Approval

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

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.
