INSTALLATION
Requirements for installation in hazardous area
Zone 1
Humidity / Dew point transmitter FA 300-2 Ex is only allowed to be connected to an intrinsic safe
circuit, in which an electrically isolated supply and signal circuit in the power supply is preferred.
Equipment without electrical isolation according to EN 50020 must not be used, if a potential
equalization occurs along the wire. The related requirements according to EN 60079-14 have to
be met.
Uo = 30 V max.
Io = 100 mA max.
Po = 1 W max.
The maximum effective inner capacity is 17 nF, the maximum effective inner inductance is neglec-
table.
4 to 20 mA analogue output
