NOTICE
Potential eqalization
The FUS060 enclosure must be connected with an earth wire to the PE connector, which is
between the cable glands.
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
2
).
Note
• Use signal cables with shielded wire pairs if analog output and pulse/frequency output are
to be used simultaneously and signals are transmitted in one cable.
• For full performance at 10 KHz frequency on digital output 1, the capacitive load should
not exceed 100 nF (see also technical specification for digital output 1).
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. Tighten the cable glands and check strain relief.
8. Lay cables in a bend in front of the cable glands to prevent moisture getting into terminal
block.
9. Screw the lid tightly on to the housing by using a tool. The sealing ring must be clean and
undamaged.
10.Remount the lid lock.
