Environment and Enclosure
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.
EXPLOSION HAZARD -
• Do not disconnect equipment unless power
has been removed or the area is known to be

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

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 not intended for use in residential environments and may not provide adequate protection to radio
communication services in such environments.
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 or be approved for the application 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.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1 , for additional installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosures.
