Preface
European Hazardous Location Approval
The following applies when the product bears the Ex Marking.
This equipment is intended for use in potentially explosive atmospheres as defined by European Union Directive 94/9/EC and has been found to
comply with the Essential Health and Safety Requirements relating to the design and construction of Category 3 equipment intended for use in
Zone 2 potentially explosive atmospheres, given in Annex II to this Directive.
Compliance with the Essential Health and Safety Requirements has been assured by compliance with EN 60079-15 and EN 60079-0.
ATTENTION: This equipment is not resistant to sunlight or other sources of UV radiation.
WARNING:
• This equipment shall be mounted in an ATEX-certified enclosure with a minimum ingress protection rating of at least IP54 (as
defined in IEC60529) 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.
• 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.
• This equipment must be used only with ATEX certified Rockwell Automation backplanes.
• 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.
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 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
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.
WARNING: EXPLOSION HAZARD -
• 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 2.
• If this product contains batteries, they must only be
changed in an area known to be nonhazardous.
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.
