11.2 ATEX Intended use
The Control Module QC03..P1.. of the FieldQ
pneumatic actuator are Group II category 1
equipment and intended for use in areas in which
explosive atmospheres caused by mixtures of air
and gases, vapours, mists or by air/dusts are likely
to occur.
The pneumatic actuator part, together with the
pneumatic Module part of the FieldQ pneumatic
actuators is a Group II category 2 equipment and
intended for use in areas in which explosive
atmospheres caused by mixtures of air and gases,
vapours, mists or by air/dusts are likely to occur.
Therefore it may be used in (ATEX) classified
Zones 1, 2 (Gasses) and/or 21, 22 (Dust).
11.3 Special conditions for safe use
(ATEX).
The material for the Control Module housing is an
aluminum alloy. When the unit is used in a
potentionally explosive atmosphere, requiring
ATEX equipment category 1 G, the unit must be
installed in such a way, that even in the event of
rare incidents, an ignition source due to impact or
friction between the enclosure and iron/steel is
prevented.
For applications in explosive atmospheres caused
by air/dust mixtures and where category 1D
apparatus is required, the surface temperature has
been determined for a dust layer with a thickness
of 5 mm maximum.

Control Module QC03 complies to the dielectric
strength requirement according IEC- 60079-11
