Series/Parallel switch
Where a 12 Volt circuit is fitted the installation of a series- paral-
lel switch can be used to:
• connect 2 (12 Volt) batteries in series during use in order to
provide the necessary 24 Volts to operate the 24 Volt bow
thruster.
• connect the 2 (12 Volt) batteries in parallel to the 12 Volt
charging system during charging.
Vetus can supply a series/parallel switch that is already fitted
with the necessary help relay to allow a simple connection to
the Vetus bow thruster, Vetus art. code: BPSP . If the batteries
installed for the bow thruster are also to be used for other (12
Volt) equipment then the following must be taken into consider-
ation:
- Both batteries will supply 12 Volt current via the charging
cables and the charging contacts of the series/parallel switch
to the other 12 volt users.
- The maximum continuous current that may flow through the
charging contacts of the series/parallel switch is 60 A.
Never use these batteries as starter batteries and never con-
nect an anchor winch to them.
The way in which the bow thruster is controlled remains
unchanged after installation of the series/parallel switch!

Electrical installation

Check that the voltage, recorded on the motor type plate, is in
agreement with the vessel's circuit voltage. Position the battery
or batteries as close as possible to the bow thruster; the main
power supply cables can then be short, which reduces the volt-
age drop as much as possible.
Connect the main power supply cables.
Fit the control panel next to the steering position. There must be
at least 50 mm space behind the panel.
Operation manual and installation instructions Bow thruster 80 kgf, ø 185 mm
Fit the control cable
between the bow
thruster and the con-
trol panel through
the vessel and con-
nect the jack con-
nections together.
If it is necessary to
cut the intermediate
cable and reconnect
it take care to ensure
the correct colours
are connected
together. N.B: The colours of the wire cores in the intermediate
cable may differ from the wire core colours as used on the bow
thruster motor and on the control panel!
A time-delay (BPTD) can be
fitted between the bow
thruster motor and the oper-
ating panel switch. This
allows the electric motor to
come to a stop when a switch
is made from port to star-
board (or vice-versa) in one
movement.
If there are two steering positions, the second control panel can
be connected to the first one.
Consult with Vetus den Ouden N.V. if two separate switches are
used instead of a Vetus control panel
12 V
If it is found during test running that the thrust direction does not
correspond with the direction switch on the control panel then
the blue (no. 1) and the white (no. 4) wires on the relay must be
interchanged.
WARNING
Do NOT test the bow thruster while the ship is out of
water, unless you are certain that everyone is at a safe
distance from the thrust tube.
Never allow the bow thruster to run for longer than 5
seconds with the ship out of water.
