5.1 Installation in the Ex area (class I, zone 2) Ambient temperature in hazardous areas
(class I, zone 2)
Observe the derating curves.
Observe the special temperature conditions according to
the rating plate.
5.2 Installation in areas with a danger of dust
explosions
WARNING: Explosion hazard
The device should be installed in a housing
(control or distributor box) that fulfills the re-
quirements of EN60079-15:2010
(IEC60079-15:20104th ED.) and at least
IP54 (EN/IEC60529) degree of protection.
WARNING: Explosion hazard
The device must be used in no more than a
pollution degree2 environment as defined by
EN/IEC60664-1.
WARNING: Explosion hazard
When installing and connecting the supply
and signal circuits observe the requirements
of EN/IEC60079-14. Only devices suitable
for operation in Ex zone2 and the conditions
at the application site may be connected to
the circuits in zone2.
In potentially explosive areas, only connect
and disconnect cables when the power is dis-
connected.
WARNING: Explosion hazard
The device must be stopped and immediately
removed from the Ex area if it is damaged or
was subject to an impermissible load or
stored incorrectly or if it malfunctions.
WARNING: Explosion hazard
The device is not designed for use in atmo-
spheres with a danger of dust explosions.
