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.
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.
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.
