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.

Publication 1734-IN582B-EN-P - February 2005

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.

ATTENTION POINT I/O is grounded through the DIN rail to

chassis ground. Use zinc-plated, yellow-chromated

steel DIN rail to assure proper grounding. Using

other DIN rail materials (e.g., aluminum, plastic,

etc.) which can corrode, oxidize or are poor

conductors, can result in improper or intermittent

platform grounding.

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-IN582B-EN-P - February 2005

Before You Begin

To effectively use your adapter, note the following considerations.

Understand Messaging

Class 3 (Explicit Message) requests through the 1734-ACNR adapter to

a specific POINT I/O module may not always receive a response

from the I/O module. In the case where the I/O module does not

reply to the request, the adapter responds with an error code

indicating a time-out.

Establish I/O Connections

When you power up a POINT I/O system and establish I/O

connections, the outputs transition to the Idle state, applying Idle

state data before going to RUN mode. This occurs even when the

controller making the connection is already in RUN mode.

Configure Autobaud

The adapter cannot reconfigure an I/O module that you previously

configured to operate at a fixed baud rate. When you reuse a POINT

I/O module from another POINT I/O system, configure the module

to autobaud before using it with the 1734-ACNR adapter.

Install the ControlNet Adapter

To install the adapter on the DIN rail prior to installing other base

units, proceed as follows.

1. Position the adapter vertically above the DIN rail.

2. Press down firmly to install the adapter on the DIN rail. The

locking mechanism will lock the adapter to the DIN rail.

3. Set the node address on the node address thumbwheel.

4. Remove the safety end cap by sliding it up. This exposes the

backplane and power interconnections.

ATTENTION You must use Series C Point I/O modules with the

1734-ACNR. Series A and B Point I/O modules will

not work with the 1734-ACNR.

WARNING If you connect or disconnect the ControlNet

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 Do not discard the end cap. Use this end cap to

cover the exposed interconnections on the last

mounting base on the DIN rail. Failure to do so

could result in equipment damage or injury from

electric shock.

Publication 1734-IN582B-EN-P - February 2005

Set the Node Address

Set the node address using the 2-position thumbwheel switch. Valid

settings range from 01 to 99. Press the + or - buttons to change the

number.

Install a Replacement ControlNet Adapter to an Existing System

ATTENTION You must use Series C Point I/O modules with the

1734-ACNR. Series A and B Point I/O modules will

not work with the 1734-ACNR.

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.
