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
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

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 meters (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.
In addition to 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.
ATTENTION
FLEX 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
Preventing Electrostatic Discharge
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.
•
Store the equipment in appropriate static-safe packaging when not
in use.
European Zone 2 Certification (The following applies when the product bears the
Ex or EEx Marking)
This equipment is intended for use in potentially explosive atmospheres as defined by
European Union Directive 94/9/EC and has been found to comply with the Essential Health
and Safety Requirements relating to the design and construction of Category 3 equipment
intended for use in potentially explosive atmospheres, given in Annex II to this Directive.
Compliance with the Essential Health and Safety Requirements has been assured by
compliance with EN 60079-15.
IMPORTANT
Observe the following additional Zone 2 certification requirements:
•
This equipment is not resistant to sunlight or other sources of UV
radiation.
•
This equipment must be installed in an enclosure providing at least
IP54 protection when applied in Class I, Zone 2 environments.
•
This equipment shall be used within its specified ratings defined by
Allen-Bradley.
•
Provision shall be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 40% when applied in
Class I, Zone 2 environments.
•
Secure any external connections that mate to this equipment by using
screws, sliding latches, threaded connectors, or other means provided
with this product.
•
Do not disconnect equipment unless power has been removed or the
area is known to be nonhazardous.
