• Store the equipment in appropriate static-safe packaging when not in use.
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:
Explosion Hazard –
• Do not disconnect equipment unless power has been removed or

The following applies to products marked
   II 3 G. Such modules:
• Are Equipment Group II, Equipment Category 3, and comply with the Essential Health and Safety Requirements relating to the design and construction of such 
equipment given in Annex II to Directive 2014/34/EU. For details, see the EU Declaration of Conformity from the 1719 Certification Bulletin, publication 1719-CT001.
• Are intended for use in areas in which explosive atmospheres caused by gases, vapors, mists, or air are unlikely to occur, or are likely to occur only infrequently and 
for short periods. Such locations correspond to Zone 2 classification according to ATEX directive 1999/92/EC.
• The I/O modules are associated apparatus with outputs leading into Category 1 
[Zone 0 (gas) or Zone 20 (dust)].
