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.
WARNING: 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

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.
WARNING: 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: When you connect or disconnect the Removable Terminal Block (RTB) with field side 
power applied, 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.
WARNING: When used in a Class I, Division 2, hazardous location, this equipment must be 
mounted in a suitable enclosure with proper wiring method that complies with the governing 
electrical codes.
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.
WARNING: Do not connect directly to line voltage. Line voltage must be supplied by a suitable, 
approved isolating transformer or power supply having short circuit capacity not exceeding 
100 VA maximum or equivalent.
WARNING: If 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. Be sure that power is 
removed before proceeding.
WARNING: Do not unscrew the RTB hold down screws and remove the RTB while power is on. 
This could cause an explosion in hazardous location installations. Be sure that power is removed 
before proceeding.
