Table 9 - 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.
