WARNING : The enclosure is manufactured from light metal. In rare cases, ignition
sources due to impact and friction sparks could occur. This shall be considered
during installation, particularly if the equipment is installed in a zone 0 location.
WARNING : Potential Electrostatic Discharge Hazard - clean the surface with a
damp cloth
AVERTISSEMENT : Le boîtier est fabriqué en métal léger. Dans de rares cas, des
sources d’inflammation due à des étincelles d’impact et de friction pourraient sur-
venir. Ceci doit être considéré lors de l’installation, en particulier si le matériel est
installé dans un emplacement 0 de la zone.
