Installing Your DeviceNet Adapter Module
ATTENTION
To comply with the CE Low Voltage Directive (LVD), this equipment
must be powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage
(PELV).
ATTENTION
To comply with UL restrictions, this equipment must be powered
from a source compliant with the following:
Class 2 or Limited Voltage/Current.
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 wriststrap.
 Do not touch connectors or pins on component boards.
 Do not touch circuit components inside the equipment.
 If available, use a static-safe workstation.
European Zone 2 Certification (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.
WARNING
Observe the following additional Zone 2 certification
requirements.
 This equipment is not resistant to sunlight or other sources
of UV radiation.
 This equipment must be installed in an enclosure providing
at least IP54 protection when applied in Zone 2
environments.
 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 40%
when applied in Zone 2 environments.
 This equipment must be used only with ATEX certified
Rockwell Automation Terminal Bases.
 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.
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.
