Please note: For a 12 Volts ship’s circuit you need to install a series-parallel switch to be able to charge the system on 12V
and use it on 24V. The JT-50, JT-70 and JT-90 come with a connecon wire F and G as a standard accessory
for this switch.

In order to keep the ship’s circuit separate from the Jet Thruster baery/baeries it is recommended to divide the charging
current with a diode bridge or MosFet baery separator from the alternator.
Please note: More electricity will be required as a result of the installaon of the Jet Thruster. That is why in some cases it is
recommended for the alternator to be converted to high yield or to place a separate alternator.
Please note: Place baeries directly next to the pump unit.
Keep baery cables as short as possible to avoid voltage drop and loss of energy.
The electric motor of the Jet Thruster generates a lot of power in a short period of me. It is necessary to
connect dedicated baeries to the system. It is necessary to make the connecon between this baery and the
system as short as possible. Use appropriate baery cables and connecng material for this at all mes.
The system must be equipped with the included main fuse, which must be installed in the baery posive cable.
For safety reasons, the Jet Thruster should be provided with a suitable main switch (not included).
The joysck operates on 12V. For vessels with a 24V installaon, a DC-DC converter must be applied.
