6.2 Electrical data for operation in zones 2, 21, 22 / Div. 2
6.2.1 Devices with HART protocol
When operating in potentially explosive areas, observe the following electrical data for the signal inputs and outputs of the transmitter. For the
correct current output design (active/passive), see the marking contained in the device's terminal box.
Model: FEP315, FEH315 / FEP515, FEH515 or FET325 / FET525

All inputs and outputs are electrically isolated from each other and from the supply power.
6.2.2 Devices with PROFIBUS PA or FOUNDATION fieldbus
When operating in potentially explosive areas, observe the following electrical data for the signal inputs and outputs of the transmitter. For the
correct design (PROFIBUS PA or FOUNDATION fieldbus), see the marking contained in the device's terminal box.
For devices in Zone 2 / Div. 2 the bus termination must conform to the FNICO model or the explosion protection regulations, respectively.

6.3 Temperature data for operation in Zone 2 / Div. 2
Model name Surface temperature
FEP315 / FEH315
FEP515 / FEH515 70 °C (158 °F)
FEP325 / FEH325
FEP525 / FEH525 85 °C (185 °F)
FET325 / FET525 70 °C (158 °F)
The surface temperature depends on the fluid temperature.
With increasing fluid temperature > 70 °C (> 158 °F) or > 85 °C (> 185 °F) the surface temperature also increases to the level of the fluid
temperature.
Note
The maximum permissible fluid temperature depends on the lining and flange material, and is limited by the operating values in Table 1 and the
explosion protection specifications in Tables 2 ... n.
