European Hazardous Location Approval
The following applies to products marked
II 3 G:
• Are intended for use in potentially explosive atmospheres as defined by European Union Directive 2014/34/EU 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.
• Are Equipment Group II, Equipment Category 3, and comply with the Essential Health and Safety Requirements relating to the design and construction of such equipment
given in Annex II to EU Directive 2014/34/EU. See the EU Declaration of Conformity at
for details.
• The type of protection is Ex nA IIC T4 Gc according to EN 60079-15.
• Comply to Standards EN 60079-0:2012, EN 60079-15:2010, reference certificate number DEMKO 14 ATEX 1342501X.
• Are intended for use in areas in which explosive atmospheres caused by gases, vapors, mists, or air are unlikely to occur, or are likely to occur only infrequently and for short
periods. Such locations correspond to Zone 2 classification according to ATEX directive 2014/34/EU.
IEC Hazardous Location Approval
The following applies to products with IECEx certification:
• Are intended for use in areas in which explosive atmospheres caused by gases, vapors, mists, or air are unlikely to occur, or are likely to occur only infrequently and for
short periods. Such locations correspond to Zone 2 classification to IEC 60079-0.
• The type of protection is Ex nA IIC T4 Gc according to IEC 60079-15.
• Comply to Standards IEC 60079-0: 2011, IEC 60079-15: 2010 reference IECEx certificate number IECEx UL 14.0066X.
WARNING: Special Conditions for Safe Use:
• This equipment is not resistant to sunlight or other sources of UV radiation.
• This equipment shall be mounted in an ATEX/IECEx Zone 2 certified enclosure with a minimum ingress protection rating of at least IP54 (in accordance with
EN/IEC 60079-0) and used in an environment of not more than Pollution Degree 2 (as defined in EN/IEC 60664-1) when applied in Zone 2 environments. The
enclosure must be accessible only by the use of a tool.
• This equipment shall be used within its specified ratings defined by Rockwell Automation.
• Provision shall be made to prevent the rated voltage from being exceeded by transient disturbances of more than 140% of the peak rated voltage when
applied in Zone 2 environments.
• This equipment must be used only with ATEX/IECEx 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.
• Earthing is accomplished through mounting of modules on rail.
• Devices shall be used in an environment of not more than Pollution Degree 2.
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.
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.
