In the event of temperature (T
p
) at the process connection, the permitted ambient temperature (T
a
)
is reduced as indicated in the following diagram (temperature derating):

1) In the case of PROFIBUS PA and FOUNDATION Fieldbus, the temperature derating depends on whether
the switch output (terminals 3 and 4) is used (G

) or not (G
1
).
