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.

Environment and Enclosure
IMPORTANT
Identifies information about practices or circumstances that can
lead to personal injury or death, property damage, or economic
loss. Attentions help you to identify a hazard, avoid a hazard and
recognize the consequences.
SHOCK HAZARD
Labels may be located on or inside the equipment, for example, a
drive or motor, to alert people that dangerous voltage may be
present.
BURN HAZARD
Labels may be located on or inside the equipment, for example, a
drive or motor, to alert people that surfaces may be dangerous
temperatures.
ATTENTION
This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as
defined in IEC 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 11. Without appropriate
precautions, there may be difficulties with electromagnetic
compatibility in residential and other environments due to
conducted and radiated disturbances.
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,
Rockwell Automation publication
1770-4.1, for additional
installation requirements.
• NEMA Standard 250 and IEC 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.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging
when not in use.
ATTENTION
POINT 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
Do not wire more than 2 conductors on any single terminal.
