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.
Meter design for NEPSI intrinsic safety,
ATEX/IECEx intrinsic safety (Zone 0 /20),
and cFMus division 1, Zone 0/20
Meter design for NEPSI combined C5 + C6, Ex protection code
is C7.
Meter design for ATEX/IECEx combined E5 + E6, Ex protection
code is E7.
Meter design for cFMus, combined F3 + F4, Ex protection code
is F8.
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.
