 1756-IN584B-EN-P - August 2003

Removal and Insertion Under Power

Be sure that power is removed or the area is nonhazardous before 
proceeding. Repeated electrical arcing causes excessive wear to 
contacts on both the module and its mating connector. Worn contacts 
may create electrical resistance that can affect module operation.

North American Hazardous Location Approval

!

WARNING

When you insert or remove the module while backplane 
power is on, an electrical arc can occur. This could cause 
an explosion in hazardous location installations.

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.
