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 publication 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.

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 na meplate indicating the hazardous location temperature code. When combining products within a system, the most adverse temperature code (lowest "T" number) m ay 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 Authorit y Having Jurisdiction at the time of installation.

WARNING

EXPLOSION HAZARD -

• Do not disconnect eq uipment unless power has been removed or the area is known to be nonhazardous.

• Do not disconnect connections to this equipment unless power has been removed or the area is known to be nonhazardous. Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this product.

• Substitution of components may impair suitability for Class I, Division 2.

• If this product contains batteries, they must only be changed in an area known to be nonhazardous.

Informations sur l’utilisation de cet équipement en environnements dangereux.

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 marqua ges sur sa plaque d'identification qui indiquent le code de température pour les environnement s dangereux. Lorsque plusieurs produits sont combinés dans un système, le code de température le plus défavorable (co de de température le plus faible) peut être utilisé pour déterminer le code de température global du système. Les comb inaisons d'équipements dans le système sont sujettes à inspection pa r les autorités locales qualifiées au moment de l'installation.

AVERTISSEMENT

RISQUE D’EXPLOSION –

• Couper le courant ou s'assurer que l'environnement est classé non dangereux avant de débrancher l'équipement.

• Couper le courant ou s'assurer que l'environnement est classé non dangereux avant de débrancher les connecteurs. Fixer tous les connecteurs externes reliés à cet équipement à l'aide de vis, loquets coulissants, connecteurs filetés ou autres moyens fournis avec ce produit.

• La substitution de composants peut rendre cet équipement inadapté à une utilisation en environnement de Classe I, Division 2.

• S'assurer que l'environnement est classé non dangereux avant de changer les piles.

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.

About the Module

The module provides EtherNet/IP connectivity. Use the tap to support linear, star, and device-level ring (DLR) topologies. The module is configured by default to support linear and star topologies. When setting up a DLR, follow the steps in the section on page 15 to avoid adversely impacting your network.

Refer to the EtherNet/IP Ring Topology Application Guide, publication ENET-AP005, for information on setting up EtherNet/IP network topologies.

Set the Network Address

The module is shipped with the rotary switches set to 999 and BOOTP enabled. You can set the network Internet Protocol (IP) address three ways.

• Use the rotary switches on the top of the module.

• Use a BOOTP server or Dynamic Host Configuration Protocol (DHCP) server.

• Use Rockwell Automation RSLinx Classic or RSLogix 5000 software.

Use the Rotary Switches

31587

Item Description

1 Front of module

2 Top of module

3 Rotary switches

The module reads the rotary switches first to determine if they are set to a valid number for the last portion of the IP address. Valid numbers range from 001…254.

When the switches are set to a valid number, the module’s IP address is

.168.1.xxx (where xxx represents the number set on the switches). The

192 module’s subnet mask is 255.255.255.0 and the gateway address is set to

0.0.0.0. The module does not have a host name assigned, nor does it use any Domain

me System when using the rotary switch settings.

1. To reset the module to its initial out-of-the-box settings, reset the tches to 888 and cycle power.

swi

IMPORTANT

Do not use the 888 switch setting during normal module operation.

2. After cycling power with the switches set to 888, remove the module

and set the switches to their final value.

The software configuration determines the IP address when you set

e rotary switches to:

• a value other than 888.

• the valid IP address values 001…254.
