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

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

module could cause damage on power up.

Publication 1797-5.5 - September 2011

To install the module on a 1797 terminal base, see the figure and complete the

following.

1. Rotate keyswitch (1) on terminal base unit (2) clockwise to position 3

(1797-IE8 and 1797-IE8NF) or position 8 (1797-IE8H) as required

for the particular 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/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 unit.

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.

Wire the Module to a 1797-TB3 or 1797-TB3S Terminal Base Unit

Module Wiring

1. Connect the individual input wiring to (+) terminals (0, 4, 8, 12) on

the 0…15 row (A) and on the 16…33 row (B) (terminals 17, 21, 25,

29) as indicated in the table, Wire Connections on page 11.

2. Connect the associated input to the corresponding (sig) terminal (1, 5,

9, 13) on the 0…15 row (A), and on the 16…33 row (B) (terminals 18,

22, 26, 30) for each input as indicated in the table, Wire Connections

on page 11.

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.
