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 to identify a hazard, avoid a hazard, and

recognize the consequences.

SHOCK HAZARD

Labels may be on or inside the equipment, for example, a drive or

motor, to alert people that dangerous voltage may be present.

BURN HAZARD

Labels may be on or inside the equipment, for example, a drive or

motor, to alert people that surfaces may reach dangerous

temperatures.

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

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

connect or disconnect the ControlNet cable (BNC or NAP) with

power applied to the 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

The Network Access Port (NAP) is intended for temporary local

programming purposes only and not intended for permanent

connection. If you connect or disconnect the NAP 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

Personnel responsible for the application of safety-related

programmable electronic systems (PES) shall be aware of the safety

requirements in the application of the system and shall be trained

in using the system.
