European Hazardous Location Approval

ATTENTION:
• 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 Directive 94/9/EC. See the EC
Declaration of Conformity at http://www.rockwellautomation.com/products/certification 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
DEMKO13ATEX1355620X.
• 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 1999/92/EC.
WARNING:
• This equipment shall be mounted in an ATEX Zone 2 certified enclosure with a minimum ingress protection
rating of at least IP54 (as defined in EN 60529) and used in an environment of not more than Pollution Degree 2
(as defined in EN 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 rated voltage when applied in Zone 2 environments.
• The instructions in the user manual shall be observed.
• Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous.
• The USB port is intended for temporary local programming purposes only and not intended for permanent
connection. Do not use the USB port in hazardous locations.

North American Hazardous Location Approval

ATTENTION:
• 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.
ATTENTION:
• 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.
• S
ubstitution 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.
WARNING:
• 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.
• If you connect or disconnect the communications cable with power applied to this module or any device on the
network, an electrical arc can occur. This could cause an explosion in hazardous location installations.
• 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.
• When you insert or remove the SD memory card while power is on, an electrical arc can occur. This could cause
an explosion in hazardous location installations.
• Do not use the USB port in hazardous locations.
