Installation recommendations for thrusters
8.4 Fuse
In addition to the main switch, a fuse must be included in the ‘posi-
tive cable’.
The fuse prevents the bow thruster from overloading, as well as pro-
tecting the onboard network from short circuiting.
Consult the table in your bow thruster installation and operating
manual for the correct fuse.
We can also provide a fuse holder for all types of fuses. Vetus art.
code: ZEHC100.
8.5 Series-parallel switch
Bow and stern thrusters that are only available for 24 Volts*) can be
connected to a 12 Volt onboard network with the help of a series-
parallel switch.
By installing a series-parallel switch:
- the 2 (12 Volt) storage batteries will be engaged in series during
use, so that the 24 Volt bow thruster receives the necessary 24
Volts of power.
- the 2 (12 Volt) storage batteries will be engaged in parallel during
recharging, and can be coupled to the 12 Volt charging system.
Vetus can provide a series-parallel switch that is ready to be connect-
ed to the Vetus 24 Volt bow thruster. Vetus art. code: BPSPE.
If the battery that has been installed for the bow thruster will also be
powering other (12 Volt) systems, the following must be taken into
account:
Both batteries will be providing power to 12 Volt systems via the
charging current cables and charging current contacts of the series-
parallel switch.
W
arning
A continuous stream of at most 100A may be carried through
the charging current contacts of the series-parallel switch, and
at most an intermittent current of 150A at 20% duration of en-
gagement.
Never use these storage batteries as starting batteries and never
connect an anchor capstan to them.
T
ip
If an isolating switch is included in the charging current cable,
the storage battery sets can be isolated, should they not be
charged for a long period of time, in order to prevent excessive
discharging.
The way in which the bow thruster is to be operated will remain un-
changed after a series-parallel switch has been installed!
*) the Vetus bow thruster BOW28548 can be connected to a 24 Volt
onboard network with the help of the series-parallel switch sup-
plied.

Bow thruster operation
Consult the Vetus catalogue for the various operating panels that are
available.
9.1 Delay when reversing the turn direction
If a delay is desired where one of the following operating devices is
installed, a delay switch can be installed.
Operating device:
- BPJSTA, separate turn switch (Joystick),
- BPSM, operating panel for side mounting,
- FSxx, foot switch button
