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 we use notes to make you aware of safety considerations.

Environment and Enclosure
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, for additional
installation requirements, Allen-Bradley publication 1770-4.1.
• NEMA Standards 250 and IEC 60529, as applicable, for explanations of
the degrees of protection provided by different types of enclosure.
ATTENTION
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 (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.

Prevent Electrostatic Discharge
Removal and Insertion Under Power
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.
• Post a sign near these modules:
Attention! Avoid electrostatic charging.
ATENÇÃO! PREVENIR CONTRA O ACÚMULO DE CARGA
ELETROSTÁTICA
For your convenience, a sign that can be cut out and posted is included
in this publication.
WARNING
These modules are designed so you can remove and insert them under
power. However, take special care when removing or inserting modules in an
active process. I/O attached to any module being removed or inserted can
change states due to its input/output signal changing conditions.
If you insert or remove the terminal base 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.

Install the Module
Read this for information about how to install the module which must be
used with a 1797-TB3 or 1797-TB3S intrinsically safe terminal base unit.
ATTENTION
This equipmment is considered Group 1, Class A industrial equipement
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 accessiblity 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 infromation regarding specific enclosure type ratings
that are required to comply with certain productsafety certifications.
ATTENTION
During mounting of all devices, be sure that all debris (such as metal chips or
wire strands) is kept from falling into the module. Debris that falls into the

To install the module on a 1797 terminal base, see the figure and complete the
following.
1. Rotate the keyswitch (1) on the terminal base (2) clockwise to position
4 as required for this type of module.
2. Make certain the flexbus connector (3) is pushed all the way to the left
to connect with the neighboring terminal base or adapter.
3. Make sure the pins on the bottom of the module are straight so they
align properly with the connector in the terminal base.
4. Position the module (4) with its alignment bar (5) aligned with the
groove (6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit,
noting that the module is seated when the latching mechanism (7) is
locked into the module.
6. Remove cap plug (8) and attach another intrinsically safe terminal base
unit to the right of this terminal base unit if required.
ATTENTION
Do not remove or replace a Terminal Base unit while power is applied.
Interruption of the backplane can result in unintentional operation or machine
motion.
IMPORTANT
Do not change the position of the keyswitch after wiring the terminal base
unit.
IMPORTANT
You cannot install the module unless the connector is fully extended.
IMPORTANT
Make certain that you only connect terminal base units to other intrinsically
safe system modules or adapters to maintain the integrity of the intrinsically
safe backplane.

Cyclic HART Input Data
The HART input data holds the primary variables for the "live" HART
device, and other information gathered during the normal HART scan.
Additional "documentary" data is available through the pass through message
interface in the device information tables. Pass through messages are defined
in detail in the User Manual.
IMPORTANT
The HART Input Data for a channel may be zeroes if HART communications is
disabled for that channel. For more information on disabling HART
communications, refer to the Disable HART communications and HART CMD
3 Disable functions in the Configuration Map table.
