North American Hazardous Location Approval
Environment and Enclosure
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.

ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage 
Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 m (6562 ft) 
without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 
11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic 
compatibility in other environments due to conducted as well as radiated disturbance.
This equipment is supplied as open-type equipment. It must be mounted within an enclosure that is 
suitably designed for those specific environmental conditions that will be present and appropriately 
designed to prevent personal injury resulting from accessibility to live parts. The enclosure must have 
suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame 
spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic. The interior of the enclosure must be 
accessible only by the use of a tool. Subsequent sections of this publication may contain additional 
information regarding specific enclosure type ratings that are required to comply with certain product 
safety certifications.
In addition to this publication, see:
•Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1
, for additional 
installation requirements.
•NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the 
degrees of protection provided by different types of enclosure.
