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 nameplate ind icating the hazardous location temperatu re code. When combining products within a system, the most adverse temperature code (lowest “T” number) may be used to help determine the overall temperature cod e of the system. Combinations of equipment in your syst em are subject to investigation by the local Authority Having Jurisdiction at the time of installa tion.

EXPLOSION HAZARD -

WARNING

• Do not disconnect equipment 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

• 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 mar quages sur sa plaque d’identification qui indiquent le co de de température pour les environnements dangereux. Lorsque plusieurs prod uits sont combinés dans un système, le code de température le plus défavorable (code de température le plus faible) peut être utilisé pour déterminer le code de temp érature global du système. Les combinaisons d’équipements dans le système sont sujettes à inspection par 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 1, Division 2.

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

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 Publication 11. Without appropriate precautions, there may be potential 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.

Besides this publication, see:

• Industrial Automation Wiring and Grounding Guidelines, for additional installation requirements, publication 1770-4.1

Publication

• NEMA Standards 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure.

Preventing Electrostatic Discharge

ATTENTION

WARNING

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.

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.

If you connect or disconnect wiring while the field-side 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

ATTENTION

Personnel responsible for the application of safety-related programmable electronic systems (PES) shall be aware of the safety requirements in the application of the system and shall be trained in using the system.
