IMPORTANT (NOTE)
For applications in US and Canada, when the temperature
under rated conditions is higher than 60 °C at the entry point or
60 °C at the branching point of conductors, accessories such as
cable, gland or conductors in conduit with minimum
temperature specification of 60 °C must be selected .
IMPORTANT (NOTE)
The devices may only be operated in explosive areas if the
housing covers have been fully closed .
WARNING
Static hazard clean only with a damp cloth .
Avertissement – Danger statique Nettoyez uniquement avec
un chiffon humide .
