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 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.

ControlLogix Ethernet Communication Interface Module 5

Publication 1756-IN053D-EN-P - June 2002

European Zone 2 Certification

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 (1999).

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.

•When not in use, store the equipment in

appropriate static-safe packaging.

Identifying Module Components

Use this illustration to identify the external features of the Ethernet

module.

Preparing the Chassis for Module Installation

Before you install the Ethernet module, you must install and connect

a ControlLogix chassis and power supply.

For information about installing these products, refer to the

publications listed in this table.

Determining Module Slot Location

You can install the module in any slot in the ControlLogix chassis.

You can also install multiple ENET modules in the same chassis. The

figure below shows chassis slot numbering in a 4-slot chassis. Slot 0 is

the first slot and is always the leftmost slot in the rack (the first slot to

the right of the power supply).

Installing the Module in the Chassis

Align the circuit board with top and

bottom guides in the chassis.

Slide the module into the chassis. Make

sure the module backplane connector

properly connects to the chassis backplane.

The module is properly installed

when it is flush with the power

supply or other installed modules.

Removing or Replacing the Module (when applicable)

IMPORTANT If you are replacing an existing module with an

identical one, and you want to resume identical

system operation, you must install the new module

in the same slot.

Push on upper and lower module

tabs to disengage them.

Slide module out of chassis.

Publication 1756-IN053D-EN-P - June 2002

Installing or Removing the Module While Power Is Applied

You can install or remove the module while chassis power is applied.

Please observe the following precautions.

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.

Wiring the Ethernet Connector

Use either an AUI or an RJ45 connector to connect to the Ethernet

network.

For detailed Ethernet connection information, see the EtherNet/IP

Performance and Application Guide, publication ENET-IN001.

Wire the appropriate connector according to this illustration.

WARNING

When you insert or remove the module while

backplane power is on, or you connect or

disconnect the communications connectors, 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.
