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

Environment and Enclosure

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 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.

Besides this publication, see:

• Allen-Bradley publication 1770-4.1, Industrial
Automation Wiring and Grounding Guidelines, for
additional installation requirements.

• NEMA Standards publication 250 and IEC publication
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.

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.

IMPORTANT

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 (e.g. aluminum, plastic, etc.) 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.
