conformally coated to meet noxious gas requirements of ISA/ANSI-71.040

1985 Class G3 Environment.)

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.

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 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,

Rockwell Automation publication 1770-4.1,

for additional

installation requirements.

 NEMA Standard 250 and IEC 60529, as applicable, for

explanations of the degrees of protection provided by

different types of enclosure.

WARNING

When you insert or remove the module while backplane power is

on, or connect or disconnect the DeviceNet cable with power

applied to this module or any device on the network, 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.

WARNING

If you connect or disconnect the communications cable with power

applied to this module or any device on the network, 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 (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.

ATTENTION

Do not remove or replace an adapter while power is applied.

Interruption of the backplane can result in unintentional operation

or machine motion.
