5.2 Electrical data for operation in zones 1, 21, 22 / Div. 1
5.2.1 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.
Dependent upon the device design, an "active" or a "passive" output will be available. For devices designed for use in Ex Zone 1, the current
output cannot be reconfigured locally. The configuration required for the current output (active/passive) must be specified when the order is
placed.

1) For "active" current output
2) For "passive" current output
3) Only available in conjunction with passive current output
4) Intrinsically safe single-channel or multi-channel barriers (supply isolators) with resistance characteristic must be used.
All inputs and outputs are electrically isolated from each other and from the power supply.
Note
The output circuits are designed in such a way that they can be connected to both intrinsically-safe and non-intrinsically-safe circuits. It is not
permitted to combine intrinsically safe and non-intrinsically safe circuits. In the case of intrinsically safe circuits, potential equalization is
required.
The rated voltage of the non-intrinsically safe circuits is U
M
= 60 V.
Provided that rated voltage U
M
= 60 V is not exceeded if connections are established to non-intrinsically safe external circuits, intrinsic safety is
still guaranteed.
If the installation is changed from type of protection "non-intrinsically safe" to "intrinsically safe" or vice versa, the device must be checked in
accordance with the instructions contained in section 7.4 "Changing the type of protection".
