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
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.
