Atex - 'Ex I' Type Of Protection - ABB TZIDC-200 Operating Instruction

TZIDC-200, TZIDC-210, TZIDC-220 DIGITAL POSITIONER | 42/18-85-EN REV. E
Special conditions
• Before final installation, the operator needs to decide on the
use of the device, either
A) as a device with 'Ex i' intrinsically safe type of protection
or
B) as a device with 'Ex d' type of protection
and permanently mark the selected type of use 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.
• The dimensions of the flameproof joint of this equipment
partly exceed the minimum values required by
EN 60079-1:2014 or IEC 60079-1:2014 or partly down-scale the
maximum values required 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.
