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 thruster.
- 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 bat-
tery 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 propel-
ler are also used for other loads the following must be taken into
account:
both batteries will supply current to 12 Volt loads via the charging
wires and the charge current contacts of the series-parallel switch.
The maximum continuous current through the charge current
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 batteries 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 wiring 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.

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 battery 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 battery 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 prop-
erly.
