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.ab.com/manuals/gi) 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.

WARNING

Identifies information about practices or circumstances that can cause

an explosion in a hazardous environment, which may lead to personal

injury or death, property damage, or economic loss.

IMPORTANT

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.

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.

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

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.

European Zone 2 Certification (The following applies when the

product bears the EEx Marking)

This equipment is intended for use in potentially explosive atmospheres as

defined by European Union Directive 94/9/EC.

The LCIE (Laboratoire Central des Industries Electriques) certifies that this

equipment 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. The examination and test results are recorded in

confidential report No. 28 682 010.

Compliance with the Essential Health and Safety Requirements has been

assured by compliance with EN 50021.

IMPORTANT

Observe the following additional Zone 2 certification

requirements.

• This equipment is not resistant to sunlight or other

sources of UV radiation.

• The secondary of a current transformer shall not be

open-circuited when applied in Class I, Zone 2

environments.

• Equipment of lesser Enclosure Type Rating 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
