5.2.2

Devices with PROFIBUS PA or FOUNDATION Fieldbus

When operating in potentially explosive areas, observe the following electrical data for the transmitter
signal inputs and outputs. For the (PROFIBUS-PA) version, see the identification marking in the device's
terminal box.
IMPORTANT (NOTE)!
For devices in zone 2, the bus termination must comply with the FNICO model (Fieldbus NonIncendive
COncept) or the explosion protection regulations.

The surface temperature depends on the medium temperature. With an increasing medium temperature
> 70 °C (158 °F) or > 85 °C (185 °F), the surface temperature also increases to the level of the medium
temperature.
IMPORTANT (NOTE)!
The maximum admissible measurement medium temperature depends on the lining and flange material
and is limited by the operating data in table 1 and the explosion-relevant technical data in tables 2 and 3.
