accumulating in the duct, which should always re-
main empty to allow air to pass through when the
unit is switched off. (see fig. 9)
It is recommended that the drainage pipe from the anti-
siphon valve be fed into the bilge, as small amounts of
water might be drained through it during normal opera-
tion.
2.6

Drainage system

The flue gas/water drainage system of the generator
must be separate from that of the main motors
WARNING
The length of the tube from the highest point of the
drain duct to the muffler should not exceed 2 metres.
This is to prevent the water left in the drainage duct
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 muf-
fler 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.

3.0 FUEL CIRCUIT

The unit is fed by diesel fuel through the tubes marked
"DIESEL"(fig. 12) and "DIESEL RETURN" (fig. 13). 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 rub-
ber, of inner diameter 8 mm.
INFORMATION
For further information, read the engine instruction
manual, supplied by the engine manufacturer.
4.0 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
5 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
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

This connection can be made through the terminal
boards (fig. 16, ref. 1) using the cables provided already
connected to the control panel. The terminals to be used
are those marked no. 1 to no. 9 for the control cables. The
earth braid should be connected to the faston terminal
(fig. 16, ref. 2) insulating it carefully and using a pre-
insulated female faston. In making the connections it is
important to follow the numbers and colours as indicated
beside (fig. 17). Fasten the A and B cables with the
clamps provided (fig 16, ref. 3).
The control panel contains 5 LEDs for operation and
alarm (fig. 18, ref. 1), an hour counter (fig. 18, ref. 2) and
the start and stop buttons (fig. 18, ref. 3/4/5).
