1) For PROFIBUS PA and FOUNDATION Fieldbus the temperature derating depends on the usage of the
switch output. (G 1 : switch output not connected; G2: switch output connected).
2) For saturated steam applications the process temperature should not exceed 150 °C (302 °F). For higher
process temperatures use FMP54.
