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, 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, 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. Repeated electrical 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

When you connect or disconnect the Removable Terminal Block (RTB) with

field side power applied, 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.

Publication 1734-IN034B-EN-P - November 2010

Prevent Electrostatic Discharge

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.

ATTENTION

POINT 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, 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

If this equipment is used in a manner not specified by the manufacturer, the

protection provided by the equipment may be impaired.

ATTENTION

To comply with UL restrictions, field power and all connected devices must be

powered from a single source compliant with the following:

Class 2.

ATTENTION

To comply with the CE Low Voltage Directive (LVD), field power and all

connected I/O must be powered from a source compliant with the following:

Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
