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

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, and recognize the consequence
SHOCK HAZARD Labels may be on or inside the equipment (for
example, drive or motor) to alert people that
dangerous voltage may be present.
BURN HAZARD
Labels may be on or inside the equipment (for
example, drive or motor) to alert people that
surfaces may reach dangerous temperatures.
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 m (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.
Besides 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.
