Special conditions
• The positioner is designed for a maximum permissible
ambient temperature range of −40 to 85 °C (−40 to 185 °F)
• Devices that also meet the requirements for the ‘intrinsic
safety’ type of protection in accordance with the declaration
may no longer be used as intrinsically safe if they have been
previously used in the ‘flameproof enclosure’ type of
protection.
• 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 IEC 60079-1
and also down-scale the maximum required values therein.
All inquiries relating to dimensions must be directed to the
manufacturer
• Only use suited cable entries that meet the requirements of
EN 60079-1.
• 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.
