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, for

additional installation requirements, Allen-Bradley publication

1770-4.1.

•NEMA Standards 250 and IEC 60529, as applicable, for

explanations of the degrees of protection provided by different

types of enclosure.

North American Hazardous Location Approval

The following information applies when

operating this equipment in hazardous

locations:

Informations sur l'utilisation de cet

équipement en environnements dangereux:

Products marked "CL I, DIV 2, GP A, B, C, D" are suitable for

use in Class I Division 2 Groups A, B, C, D, Hazardous

Locations and nonhazardous locations only. Each product is

supplied with markings on the rating nameplate indicating

the hazardous location temperature code. When

combining products within a system, the most adverse

temperature code (lowest "T" number) may be used to help

determine the overall temperature code of the system.

Combinations of equipment in your system are subject to

investigation by the local Authority Having Jurisdiction at

the time of installation.

Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne

conviennent qu'à une utilisation en environnements de

Classe I Division 2 Groupes A, B, C, D dangereux et non

dangereux. Chaque produit est livré avec des marquages sur

sa plaque d'identification qui indiquent le code de

température pour les environnements dangereux. Lorsque

plusieurs produits sont combinésdansun système, le code de

température le plus défavorable (code de température le plus

faible) peut être utilisé pour déterminer le code de

température global du système. Les combinaisons

d'équipements dans le système sont sujettes à inspection par

les autorités locales qualifiées au moment de l'installation.

Preventing Electrostatic Discharge

About the 1756-DHRIOXT Module

You can use the 1756-DHRIOXT module to communicate on a DH+

or remote I/O network.

The 1756-DHRIOXT module functions in the same way as the

traditional 1756-DHRIO module. For information about configuring

and using both the 1756-DHRIOXT and 1756-DHRIO module, see the

ControlLogix Data Highway Plus-Remote I/O Communication

Interface Module User Manual, publication 1756-UM514.

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.

About ControlLogix-XT Systems

The ControlLogix-XT products include control and communication

system components that, when used with FLEX I/O-XT products,

provide a complete control system solution that can be used in

environments where temperatures range from -20...70 °C (-4...158 °F).

When used independently, the ControlLogix-XT system can withstand

environments where the temperature ranges from -25...70 °C

(-13...158 °F).

ControlLogix-XT with Traditional ControlLogix Components

For more information about standard ControlLogix component

specifications and installation requirements, see the resources listed

in the Additional Resources table on page 30.

IMPORTANT

ControlLogix-XT system components are rated for extreme

environmental conditions only when used properly with other

Logix-XT system components. The use of ControlLogix-XT components

with traditional ControlLogix system components nullifies

extreme-environment ratings.

If a ControlLogix-XT module is used with traditional ControlLogix products,

that is, ControlLogix products not designed for extreme environments, the

ControlLogix-XT module can withstand only the environments specified for

the traditional ControlLogix version of the module. For example, if a

1756-DHRIOXT module is used in a traditional 1756-A10 chassis, the

1756-DHRIOXT module can withstand only the environment specified for the

traditional 1756-DHRIO module.

The ControlLogix-XT system components are designed to meet the same

and greater operational and environmental requirements as traditional

ControlLogix products.

When a ControlLogix-XT component is used as a replacement for a

traditional ControlLogix component, the functional and environmental

requirements of the traditional ControlLogix component apply.

Publication 1756-IN638A-EN-P - March 2009

Before You Begin

Before you install your module, complete these tasks:

• Set the Network Type and Node Address Switches, page 10

• Prepare the Chassis for Module Installation, page 11

• Determine Module Slot Location, page 12

Set the Network Type and Node Address Switches

Before you install the module, set the network type switches for each

channel.

1. Using this image or the module label as a reference, set the

network type switches on the top of the module.

IMPORTANT

If your module uses the 230k DH+ network, that is, Channel A switch set to

3, Channel B is disabled.

Also, node address switches do not apply if you are using remote I/O.
