Introduction
By installing the series-parallel switch:
- The 12 Volt batteries are connected in series while operating
in order to provide the necessary 24 Volt for the bow thrus-
ter.
- The 12 Volt batteries are connected in parallel and coupled
to the 12 volt charging system while charging.
The series-parallel switch has been manufactured so as to allow
easy connection to a VETUS 24 V bow thruster.
If an isolating switch (# 15) is fitted in the charging wire the
battery sets can be separated if charging is not carried out
for a long time in order to prevent excessive discharging.
If the batteries (12 Volt) that have been installed for the bow
propeller are also used for other loads the following must be
taken into account:
both batteries will supply current to 12 Volt loads via the charg-
ing wires and the charge current contacts of the series-parallel
switch.
The maximum continuous current through the charge cur-
rent contacts of the series-parallel switch may not be more
than 100 A.
Therefore, never use these batteries as starter batteries
and never connect an anchor winch to these batteries!
Operating
The bow propeller can be operated as described in the 'User
Instructions' in Chapter 'Use' after installing the series-parallel
switch.
The series-parallel switch operates automatically as soon as the
bow propeller is operated and then switches off with a delay
afterwards.
Installation
Disconnect all battery wires if an existing installation is
to be extended with the series-parallel switch and 2 extra
batteries. Then install the series-parallel and the batter-
ies and wires as described in these instructions.
Fit the series-parallel switch as close as possible to the batteries
and the bow propeller in one of the illustrated positions in order
to keep the main circuit wires as short as possible. See the wir-
ing diagrams for how to connect the circuit.
Batteries
Total battery capacity: see the manual for the bow thruster.
Use batteries of the same type, capacity and length of service.
Position the batteries as close as possible to the bow propeller;
this allows the main circuit wires to be kept short so that there
will be little voltage loss.

Warning
Warning
Main circuit wires
Use main circuit wires of sufficient cross-section.
A main switch and a fuse must be fitted in the + wire to the bow
propeller.
Connect the main circuit wires and make sure that the main
switch is set to 'OFF'.
Charging wires
Use charging wires of sufficient cross-section.
Connect the charging wires.
Do not connect the alternator wire to terminal 51 on the
series-parallel switch yet.
If the same alternator is also to be used for a battery set that is
not connected through the series-parallel switch the charging
circuits must be separated by a battery isolator.
Control wires
Only connect the control wire to the panel.
Do not connect the control wire to the bow propeller yet.
Check
After installing carry out the following checks:
- Check once more that all wires have been installed as shown
in the diagram!
- Use a voltmeter to check that there is a voltage of 12 Volt
between the plus (+) of battery 1 and the minus (-) of bat-
tery 2.
Repeat this measurement between the plus (+) of battery 2
and the minus (-) of battery 1.
- Switch on the control panel and operate the direction switch;
the series-parallel switch will be switched on.
Use a voltmeter to check that there is a voltage of 24 Volt
between the plus (+) of battery 2 and the minus (-) of bat-
tery 1.
- Connect the control wire to the bow propeller and operate
the direction switch. The relay on the bow propeller must now be operated.
Now connect the charging wire from the alternator to terminal
51(+ALT) on the series-parallel switch, switch on the main
switch of the bow propeller and check that the bow propeller
operates properly.
