The plug of the system control unit must not be connected to the socket of the
electrical supply. An earth cable is absolutely necessary for connection of the
additional pump. We advise that this cable should be protected by a pipe running
from the holding tank to the rainwater usage system. Pass the end of the cable
through the threaded grommet holder provided with the housing to the SILENTIO
system control. Now open the lower cover of the system control housing (see
Figure 1). Remove the blind screw and replace this with the supplied threaded
grommet holder. Isolate the wire cores of the cable in the proper manner. Pass the
cable through the grommet opening in the system control unit housing. Connect the
protective earthing conductor (green - yellow wire core) on a free terminal with the
designation
“PE / Ground” . Connect the neutral wire core (blue) on a free
terminal with the designation “5” .
Connect the live electrical supply wire core (brown or black) on a free terminal
with the designation
“2” (power supply to the additional pump). The following
figure depicts the connections described above:
1: Pump
2: Power supply to additional pump
3: Power supply to filter flushing valve
4: Power supply to switch-over valve
5: Neutral conductor
P: 230V AC
PE / Ground : Earth

After connecting the wires, close the lower cover [7] of the system control housing.
