•
Special conditions
• The positioner is designed for a maximum permissible
ambient temperature range of −40 to 85 °C (−40 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.
• Only suited cable entries must be used that meet the
requirements of EN 60079-1.

Type Intrinsic safety 'i'
Standards IEC 60079-0, IEC 60079-11
Special conditions
• Power supply for the 'Mechanical digital feedback with
Pepperl & Fuchs SJ2-SN proximity switches' circuit must be
provided intrinsically safe and in accordance with
PTB 00 ATEX 2049 X certificate according to application
type 2.
• It is only permissible to connect, disconnect, and switch live
circuits during installation or maintenance, or for the
purpose of carrying out repairs.
Note
It is considered very unlikely that a potentially hazardous
atmosphere would be present in Zone 2 at the same time
that installation or maintenance or repair work was being
carried out.
• Only non-flammable gases must be used for pneumatic
power supply.
• Only use suited cable entries that meet the requirements of
EN 60079-11.
