4.0. ELECTRICAL CONNECTIONS
4.1.

Battery connection

To start off the unit an independent battery of 12V is
needed, capacity 18 - 30 Ah min.
It should be connected to the clamp of the generator as
shown in fig. 11 with cables of section 25 mm
distances of 5 metres and with cables of section 35 mm
for longer 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,
(the starter).
- 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
automatically recharge the start-up battery, giving 10
A, at a voltage of 12 V, when fully charged.
IMPORTANT
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
instructions for connection in reverse order.
Do not invert the poles of the connecting cables
since serious damage might be caused to the
generator 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.

Control panel connection

This connection can be made through the terminal
boards (fig. 12, 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
earths braid should be connected to the faston terminal
(fig. 12, ref. 2) insulating them carefully and using a pre-
insulated female faston. In making the connections it is
important to follow the diagram and the colours codes as
indicate (fig. 13). Fasten the cable with the provided
plastic support on the bail (fig. 12, ref. 3).

The control panel contains 5 LEDs for operation and
alarm (fig. 14, ref. 1), an hour counter (fig. 14, ref. 2) and
the start and stop buttons (fig. 14, ref. 3/4/5).
For fixing the control panel is necessary to perforate as
shown in fig.14.

The control panel is indispensable for operating
the unit and must be installed; do not use devices

Make the connections with the battery
The control panel is provided with a connecting
cable 10 metres long. This cable should not be
modified since it might cause the panel circuit to
4.3. A.C. Connection
This connection can be done through the power terminal
board (fig. 15, ref. 1) placed inside the derivation box.
This range includes the possibility of use both at 115V
50Hz - 120V 60Hz and 230V 50Hz - 240V 60Hz.
For this reason it is possible to make two types of
connection (and use), according to the following
configurations.
1 - Parallel configuration: in this configuration there is a
single output at 115 (120) V between points P
F , connecting the outputs of the alternator (P

2 - Serial connection; in this configuration it is possible
to use a voltage of 230 (240) V between points P
F , as shown in the diagram in fig. 17.

In serial connection, power can be picked up both at 110
(120) V between points F
