Connecting
5.2 Wiring output and power supply
4. Make the connection according to the following schematics.
Intrinsically safe circuits must be separated from non-intrinsically safe circuits by certified
safety isolators or barriers.
For reliable communication via HART protocol the load in the signal circuit must be at least
230 Ω.
The FUS060 enclosure must be connected with an earth wire to the PE connector.
Note
• Use signal cables with shielded wire pairs if analog output and pulse/frequency output are
• For full performance at 10 KHz frequency on digital output 1, the capacitive load should
5. Fit end ferrules to fine wire cables.
6. Connect PE cable of power supply to earth terminal in terminal box. Use a cable length so that
the PE conductor is the last one to come away when the cables are pulled.
7. Mount lid for power supply terminals.
8. Tighten the cable glands and check strain relief.
9. Lay cables in a bend in front of the cable glands to prevent moisture getting into terminal
block.
10.Replace unused cable glands with certified blanking plugs.

NOTICE
Both transmitter and sensor must be grounded for optimal performance
The PE-terminals on the FUS060 and on the sensors (SONO 3200 transducers, SONO 3100
or SONO 3300) must be connected to the local equipotential bonding system (min. 4 mm
to be used simultaneously and signals are transmitted in one cable.
