FLEX I/O PROFIBUS Adapter Module
Cat. No. 1794-APB Series B
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 we use notes to make you aware of safety considerations.

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
• recognize the consequence
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 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 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.
See NEMA Standards publication 250 and IEC publication
60529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure. Also, see
the appropriate sections in this publication, as well as the
Allen-Bradley publication 1770-4.1 ("Industrial Automation
Wiring and Grounding Guidelines"), for additional
installation requirements pertaining to this equipment.
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.
WARNING
If you connect or disconnect wiring while the field side
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..
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
(e.g. aluminum, plastic, etc.) that can corrode, oxidize, or are
poor conductors, can result in improper or intermittent
grounding.
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.
