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.

WARNING: The installation of the XM-440 module includes the following warnings:
• When you insert or remove the module while 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 connect or disconnect the serial cable with power applied to this module or the serial device on the other end of the cable,
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.
• Be sure that power is removed or the area is nonhazardous before proceeding.
• If you connect or disconnect the XMbus cable with power applied to this module or any device on the network, 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 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.
• Wiring to or from the XM-440 module, which enters or leaves the system enclosure, must utilize wiring methods suitable for Class
I, Division 2 Hazardous Locations, as appropriate for the installation in accordance with the product drawing Without Barriers - 
48240-HAZ.
