Special conditions
• The positioner is designed for a maximum permissible
ambient temperature range of 40 to 85 °C (104 to 185 °F)
• Variants that, according to declarations, also meet the
requirements for the 'intrinsically safe' type of protection
may no longer be used as 'intrinsically safe' if they have been
previously used as a flameproof 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.
