Publication 1794-IN123D-EN-P - August 2018

North American Hazardous Location Approval

The following modules are North American Hazardous Location approved: 1794-IM16, 
1794-OM16.

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 nonhazardous.

• Do not disconnect connections to this 

equipment unless power has been 
removed or the area is known to be 
nonhazardous. Secure any external 
connections that mate to this equipment 
by using screws, sliding latches, 
threaded connectors, or other means 
provided with this product.

• Substitution of components may impair 

suitability for Class I, Division 2.

RISQUE D’EXPLOSION

• Couper le courant ou s'assurer que 

l'environnement 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 fournis avec ce produit.

• La substitution de composants peut rendre cet 

équipement inadapté à une utilisation en 
environnement de Classe I, Division 2.
