The devices must be installed in a protected environment in
accordance with the specific conditions on the test certificate .
Pollution degree 3 (refer to IEC 60664-1) must not be exceeded
for the macro environment of the device . The device conforms
to degree of protection IP66 / IP67 . If the device is installed as
intended, this requirement is met by the housing as standard .
When connected to the line supply, the electrical circuits must
not exceed overvoltage category III . When not connected to the
line supply, the electrical circuits must not exceed overvoltage
category II .

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 .
