DANGER - Risk of explosion caused by incorrect transmitter installation
The FET321 / FET521 transmitter is not approved for hazardous areas.
The FET321 / FET521 transmitter must not be installed or operated in potentially explosive
atmospheres.
If the FEP325 flowmeter sensor is combined with the FET321 or FET325 transmitter (Zone 2),
the maximum permissible signal cable length is 50 m (164 ft) with a minimum conductivity of
5 µS/cm, without a pre-amplifier. The same is valid for the FEP525 flowmeter sensor with
FET521 or FET525 (Zone 2) transmitter.
If the FEP325 flowmeter sensor is combined with the FET325 transmitter (Zone 1), 10 m
(32.8 ft) signal cables are permanently connected to the transmitter. The same is valid for the
FEP525 flowmeter sensor with FET525 (Zone 1) transmitter.
