RoHS Directive
This product is only intended for use in large
scale fixed installation excluded from the scope
of Directive 2011/65/EU on the restriction of
the use of certain hazardous substances in
electrical and electronic equipment (RoHS 2).
Ambient temperature:
T4 @ Ta = -20°C...+50°C IP66/Nema 4X
10.2 ATEX/IECEx Intended use
• The Control Module QC54..P4.. of the
FieldQ pneumatic actuator is a Group II category
3 equipment with protection level Gc (IECEx).
• The pneumatic actuator part, together with the
pneumatic module part of the FieldQ pneumatic
actuators is a Group II category 2 equipment.
• Both are 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 the assembly may be used in hazard-
ous area classified Zones 2 (Gasses) and/or 21,
22 (Dust).
10.3 Safety instructions
WARNING
• Personal injury or property damage caused
by fire or explosion may occur if the module
is opened in any area which contains a
potentially explosive atmosphere or has been
classified as hazardous.
• Do not open when module is energized.
• Prevent any kind ignition during installation,
adjustment, putting into service and use.
• Assembly, disassembly and maintenance
must be done in safe area’s without a poten-
tial explosion hazard.
• Installation, adjustment, putting into service,
use, assembly, disassembly and mainte nance
of the pneumatic actuator must be done by
qualified personnel.
• Provisions must be made to prevent the
rated supply voltage being exceeded by
more than 40%.
• Potential electrostatic charging hazard, clean
only with a damp cloth - danger of propagat-
ing discharge.
• The apparatus shall be installed in such a way
that the risk from electrostatic discharges
and propagating brush discharges caused by
rapid flow of dust is avoided.
• Precaution shall be taken to avoid danger of
ignition due to electrostatic charges on the
marking plate of the enclosure.
• Substitution of electronics cartridge, switch
cartridge, pilot valve cartridge, pneumatic
cartridge, enclosure and seals must be with
parts from Emerson else the suitability for
Division 2 will be impaired.
