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 60664-1), at altitudes up to 2000 m (6562 ft) without derating.

This equipment is not intended for use in residential environments and may not provide adequate protection to radio communication services in such environments.

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 or be approved for the application if nonmetallic. 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 the following:

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 wrist strap.

• 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.

WARNING

AVERTISSEMENT

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 Authority H aving Jurisdiction at the time of installation.

EXPLOSION HAZARD -

• Do not disconnect eq uipment 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 environneme nts 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 par les autorités locales qualifiées au moment de l'installation.

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.

WARNING

ATTENTION

WARNING

• This equipment shall be mounted in an ATEX-certified enclosure with a

minimum ingress protection rating of at least IP54 (as defined in IEC 60529) and used in an environment of not more than Pollution Degree 2 (as defined in IEC 60664-1) when applied in Zone 2 environments. The enclosure must have a tool-removable cover or door. The installation of the product within an ATEX approved enclosure shall not raise the surrounding ambient temperature above the limit specified for the product.

• This equipment shall be used within its specified ratings defined by

Rockwell Automation. The XM-940 is only approved for use with ATEX approved measurement modules with relays up to 120V AC.

• Provision shall be made to prevent the rated voltage from being exceeded

by transient disturbances of more than 140% of the rated voltage when applied in Zone 2 environments.

• Secure any external connections that mate to this equipment by using

screws, sliding latches, threaded connectors, or other means provided with this product.

• Do not disconnect equipment unless power has been removed or the area

is known to be nonhazardous.

An electrical arc can occur if you do the following:

• Insert or remove the module while backplane power is on

• Connect or disconnect wiring while the field-side power is on

This can cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

Do not remove or replace a terminal base unit while power is applied. Interruption of the backplane can result in unintentional operation or machine motion.

Wiring to or from this device, which enters or leaves the system enclosure, must utilize wiring methods suitable for Class I, Division 2 Hazardous Locations, as appropriate for the installation in accordance with the product drawings as indicated in the following table.
