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.rockwellautomation.com/literature/) 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

Preventing Electrostatic Discharge

ATTENTION: This equipment is intended for use in a Pollution Degree 2

industrial environment, in overvoltage Category II applications (as defined in

EN/IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating.

This equipment is not intended for use in residential environments and may not

provide adequate protection to radio communication services in such

environments.

This equipment is supplied as open-type equipment for indoor use. 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 or be approved for the

application if nonmetallic. The interior of the enclosure must be accessible only

by the use of a tool. Subsequent sections of this publication may contain more

information regarding specific enclosure type ratings that are required to

comply with certain product safety certifications.

In addition to this publication, see the following:

• Industrial Automation Wiring and Grounding Guidelines, Rockwell

Automation publication 1770-4.1, for more installation requirements.

• NEMA Standard 250 and EN/IEC 60529, as applicable, for explanations of

the degrees of protection provided by enclosures.

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.

Publication 1794-IN096D-EN-P - June 2018

ATTENTION: This product is grounded through the DIN rail to chassis ground.

Use zinc plated chromate-passivated 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. Be sure to ground the DIN rail

properly.

Refer to Industrial Automation Wiring and Grounding Guidelines, Rockwell

Automation publication 1770-4.1, for more information

ATTENTION: If this equipment is used in a manner not specified by the

manufacturer, the protection provided by the equipment may be impaired.

ATTENTION: If this equipment is used in a manner not specified by the

manufacturer, the protection provided by the equipment may be impaired.

ATTENTION: Read this document and the documents listed in the Additional

Resources section about installation, configuration, and operation of this

equipment before you install, configure, operate, or maintain this product.

Users are required to familiarize themselves with installation and wiring

instructions in addition to requirements of all applicable codes, laws, and

standards.

ATTENTION: Installation, adjustments, putting into service, use, assembly,

disassembly, and maintenance are required to be carried out by suitably

trained personnel in accordance with applicable code of practice.

ATTENTION: In case of malfunction or damage, no attempts at repair should

be made. The module should be returned to the manufacturer for repair. Do not

dismantle the module.

ATTENTION: Use only a soft dry anti-static cloth to wipe down equipment. Do

not use any cleaning agents.

Publication 1794-IN096D-EN-P - June 2018

WARNING: When you insert or remove the module while backplane power

is on, an electric 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. Repeated electric arcing causes excessive wear to contacts on

both the module and its mating connector. Worn contacts may create

electrical resistance that can affect module operation.

WARNING: If you insert or remove the module while backplane power is on,

an electric 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.

FLEX I/O Digital Input and Output Modules with Diagnostics 7

Publication 1794-IN096D-EN-P - June 2018

Install the Isolated Analog Output Module

The input module mounts on a 1794-TB32 or 1794-TB32S terminal base. The output

module mounts on a 1794-TB2, 1794-TB3, or 1794-TB3S terminal base.

1. Rotate the keyswitch (3) on the terminal base (4) clockwise to position 4 as

required for this type of module.

2. Make sure the Flexbus connector (1) is pushed all the way to the left to connect

with the neighboring terminal base/adapter.

You cannot install the module unless the connector is fully extended.

3. Make sure the pins on the bottom of the module are straight so they will align

properly with the connector in the terminal base.

4. Position the module (7) with its alignment bar (6) aligned with the groove (5) on

the terminal base.

5. Press firmly and evenly to seat the module in the terminal base unit. The module

is seated when the latching mechanism (2) is locked into the module.
