GENERATORS
returning to the motor after filling the tank muffler,
when the unit is turned off.
1 - Tank muffler.
This dampens the noise of the drainage and stops the
water flowing back towards the motor. The muffler
should be installed no less than 1 metre away from the
generator and positioned at a height as per fig. 4/5.
2 - Silencer
This further reduces noise. It should be installed no
more than 1 metre from the sea drainage nozzle.
3 - Outboard drainage pipe.
This must be fitted in a position that is constantly
above sea level in all the vessel's possible conditions
of use.

3 FUEL CIRCUIT

The unit is fed by diesel fuel through the tubes marked
"Fuel inlet"(fig. 12 ref. 2 ) and "fuel outlet" (fig. 13 ref. 3).
This latter is used for the return of the excess fuel. There
is no need for filters in connections to the fuel tank, since
the unit already contains a fuel filter; however it is
advisable to fit a tap onto the fuel supply line downstream
of the tank and a single-acting valve (check valve) to
prevent the fuel system emptying for any reason. Use a
valve with a 50 millibar opening. (Max head 0.8 mt.)
The fuel pipes should be in hydrocarbon-resistant rubber,
of inner diameter 8 mm.
INFORMATION
For further information, read the engine instruction
manual, supplied by the engine manufacturer.
4 ELECTRICAL CONNECTIONS
4.1

Battery connection

To start off the unit an independent battery of 12V is
needed, capacity 70 Ah.
WARNING
The battery must not be smaller than the rated
capacity.
It should be connected to the terminal of the generator (fig.
15) with cables of section 25 mm
metres and with cables of section 35 mm
distances, and following the sequence of operations
described below:
- First connect the positive pole (+) of the battery to the
terminal marked with the symbol (+) on the generator.
- Then connect the negative pole (-) of the battery to the
GB
up to distances of 5
2
2 for longer
terminal marked with the symbol (-) on the generator.
- Wipe the connections with special mineral grease to
protect against oxidation and corrosion.
The generator includes an electronic device to auto-
matically recharge the start-up battery, giving
15 A, at a voltage of 12 V, when fully charged.
DANGER
Install the battery in a well-ventilated area, away
from the generator and from any device which might
produce heat or sparks.
Periodically check the state of the connections of the
terminals and the water level of the battery. If the
cables need to be disconnected, follow the instruc-
tions for connection in reverse order.
Do not invert the poles of the connecting cables
since serious damage might be caused to the gen-
erator and the battery.
Do not connect other loads to the battery.
In order to reduce galvanic currents to a minimum, the
(-) of the battery of the electric generator should not be
connected to the (-) of the other batteries on board.
4.2

Control panel connection

Two different types of terminal boards are available; to
be installed on bridge and connectable to the genset in
order to command the start/stop functions.
Both types of boards are equipped with 20mt. cable
with a plug-in socket terminal end to be fitted on the
genset.
Plug in one end of the connection cable in the socket
placed on the inner board of the genset and the
opposite end in the remote control panel ( fig.16 ref.1 ).
4.3 A.C. Connection
This connection is made through the power terminal
board located on the alternator of the generator (Fig.
14 Ref. 1). This terminal board is accessed after
having removed the closing panel as shown in Fig.13
Ref. 1.
This range of generators may be operated at both 115V
- 50Hz / 120V - 60Hz and 230V - 50Hz / 240V -60Hz.
Hence different connections (and thus uses) are
possible according to the following configurations:
1 Parallel configuration; in this configuration there is:
- 115/120V between the points 11 and 4 by connecting
the alternator outputs 33-11 and 2-4 according to the
diagram in Fig. 15 Ref. 2
2 Serial connection; in this configuration there is:
- 230/240V between the points 11 and 4 by connecting
the alternator outputs 33-2 according to the diagram
in Fig. 15 Ref. 1.
With the series connection the power may be drawn
simultaneously at a voltage of 115/230 50Hz and 120/
240V 60Hz, as per the diagrams in Fig.15 Ref.3
