Special conditions
• Before the final installation, the operator decides on the use
of the device, either
– as a device with the intrinsically safe 'Ex i' type of
protection or
– as a device with the 'Ex d' type of protection
The selected type of use must be permanently marked on the
name plate. Specific conditions of the surrounding
environment, such as chemical corrosion, must be taken into
account when affixing the permanent mark. Only the
manufacturer must change the selected type of use following
a re-examination
• Medium strength adhesive must be used to secure the cable
entries and line entries and stop them from twisting and self-
loosening
• In the case of high torsional forces, the bearing sleeves must
be replaced due to wear on the shaft for the position pickoff
(significant control deviation).
• If the positioner is operated at an ambient temperature
above 60 °C (140 °F) or below -20 °C (-4 °F), make sure to use
cable entries and lines suited for an operating temperature
corresponding to the maximum ambient temperature
increased by 10 K or corresponding to the minimum ambient
temperature, respectively.
• Only use suited cable entries that meet the requirements of
EN 60079-1.
• The dimensions of the flameproof joint of this equipment
partly exceed the minimum values required by EN 60079-1 or
IEC 60079-1 and also partly fall below the maximum required
values therein. All inquiries relating to dimensions must be
directed to the manufacturer
• Screws that comply with the minimum requirements of the
A2-70, A2-80 or 10.12 quality grades must be used to close
the flameproof enclosure.
