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.
