Introduction
By installing the series-parallel switch:
- the 2 battery sets (24 Volt, 2 x 12 Volt) are connected in series
to supply the required 48 Volts for the bow propeller while it
is operating
- the 2 battery sets (24 Volt, 2 x 12 Volt) are connected in paral-
lel to the 24 Volt charging system while charging.
The series-parallel switch is designed to allow a simple connec-
tion to the VETUS 48 V bow propeller.
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 (24 Volt) that have been installed for the bow
propeller are also used for other loads the following must be
taken into account:
both sets of batteries will supply current to 24 Volt loads via the
charging 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 about 200 Ah - 48 Volt.
(E.g. 4 starter batteries each 200 Ah - 12 Volt).
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.
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 24 Volt
between the plus (+) of battery set 1 and the minus (-) of
battery set 2.
Repeat this measurement between the plus (+) of battery set
2 and the minus (-) of battery set 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 48 Volt
between the plus (+) of battery set 2 and the minus (-) of
battery set 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.
