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.

• If this product contains batteries, they must 

only be changed in an area known to be 
nonhazardous.

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.

• S'assurer que l'environnement est classé 

non dangereux avant de changer les piles.

WARNING: 

If you connect or disconnect wiring while the field-side power is on, an 
electrical arc can occur. This could cause an explosion in hazardous 
location installations. Be sure that power is removed or the area is 
nonhazardous before proceeding.

If you insert or remove the module while backplane power is on, an 
electric arc can occur. This could cause an explosion in hazardous 
location installations. Be sure that power is removed or the area is 
nonhazardous before proceeding.

The module does not support “Removal and Insertion Under Power” 
(RIUP) capability. Do not connect or disconnect the module while power 
is applied. Be sure power is removed before proceeding.

For Class I Division 2 applications, use only Class I Division 2 listed or 
recognized accessories and modules approved for use within the 1794 
platform.
