Comment: It is considered veryunlikely that a potentially explosive atmosphere would be present in zone 2 at the same timethat installation or maintenance/repair work was being carried out.• Only non-flammable gases may be used for the pneumatic auxiliary power.• Only use suitable cable entries which meet the requirements of IEC 60079-15.• If the SJ2_S1N (NO) proximity switch is used, the positioner may only be operated at anambient temperature range from -25 ... 85 °C.
