Series / parallel switch box installation manual 1.0.1 - 2018
Note! To achieve maximum eect, reliability and durability from your Side-Power thruster, a cor-
rect installation as per the instructions are very important. Please follow the instructions carefully,
and make sure that all checkpoints are carefully controlled.
Introduction and planning for the installation of the Side-Power series / paral-
lel switch box.
The Side-Power series/parallel switch box have been designed to provide a safe and reliable 24V
power for a 24V thruster in a 12V boat.
It has been specially designed and built to accommodate for the high current demands of an elec-
tric thruster and are available in two versions, one for the SE170TC and one for the SP240TC.
It is also designed so that there is no need for additional charging devices and connections, the
extra battery will be automatically charged by the “original” charge feed in the boat for the stand-
ard battery (battery bank) that are being used as “Batt.1”.
There are no need to install 2 special battery banks as one of the boats “standard” banks can be
used as Batt.1, preferably the start battery bank as this is “always” full. The start battery bank is
also preferred as there are normally no electronics that can be knocked out by a voltage drop or
peak caused by all heavy electromtotors such as a thruster.
NOTE ! If you have electronically controlled engines (MMC / Volvo EDC / Morse etc.) the
power to these must not be taken from the same battery as you power a thruster (or any
other high power electric item). The best and most easy way to solve the power feed to
such sensitive and critical items is a small extra battery for this. It is less expensive to pro-
vide a separate power feed to the electronic engine controls instead of a separate battery
system for the heavy users, as the electronics have a very small power demand in compar-
ison with a thruster, windlass and the engines starter motor.
Without exceptions, Batt.2 can have no other connections other than those described in these
instructions.
We advice to install the extra battery (Batt.2) and the series / parallel switch box as close to the
battery (bank) used as Batt.1 as possible.
Make sure to use heavy duty power cables for all battery and thruster connections including the
ones between the batteries and the series/parallel box. The minimum cable size to use is 70mm2
/ OOO or more if required by the length. See list in manual for the thruster you are installing.
The series/parallel switch box is splash proof but must be installed in a dry position so that it can
not become submerged in water.
Observe and follow the minimum battery capacity ratings described here. The smallest rating is
for the SE170TC and the largest for the SE210TC & SP240TC. Remember, these are minimum
ratings, bigger is better.
Always install main power switches in the main positive cables from each battery bank so that in
case of a failure or emergency, the power can be switched o󰀨. The boat owner / operator must be
informed of the location of these switches and instructed to shut them o󰀨 when leaving the boat.
We also advice to install fuses at each battery as described in the wiring diagrams.

Series / parallel switch box installation manual 1.0.1 - 2018
When the thruster is not running: (see FIG.1)
The two batteries (battery banks) are connected in parallel so that the extra battery is being charged
by the boats normal 12V charge system, the same charge system that is charging the standard Batt.1.
By this, the extra battery (Batt.2) becomes a full part of the Batt.1 bank and thereby also increase the
capacity of this.
The box is built so that you can draw
the same amount current from the
extra Batt.2 as the thruster draws as
the solenoids have the same capacity
in their inactive position as in the ac-
tive position.(and basically nothing on
a boat draws as much as a thruster).
There is no power on the main positive
lead to the thruster until the thruster is
activated by the control panel.
The power to the thrusters control
system and panel is supplied by the
series/parallel switch box, via the grey
and black leads to the control side of
the thrusters solenoid only.

When you run the thruster: (see FIG.2)
When a run signal is sent to the thruster from the panel, the solenoids in the series/parallel box re-
acts rst so that Batt.2 is moved into a series connection with Batt.1. so that there is 24V on the main
power supply cable to the thruster.
The main contactors on the thrust-
er does not engage until this have
been done so that you have 24V at
the thruster to control the 24V main
solenoid contactors on the thruster.
Now, only Batt.1 is being charged
while Batt.2 can only draw from its
own capacity.
In this position, Batt.1 is 0 - 12V
and Batt.2 becomes the 12V -
24V portion of the 24V feed to the
thruster.
Batt.2 can only be connected to the
series/parallel switch box as de-
scribed in the manual.

Installation
1. Install the thruster as per the installation instructions following it, but disregard the wiring
diagram which are being replaced by the diagrams in this manual. Make sure to use the
correct main cable size according to the length to thruster as listed in the thrusters manual.
NOTE! The length measurements in this list is the total of the + and - cable.
2. Bolt the box to a bulkhead in an accessible location as close to the two battery banks as
possible. It should be positioned so that the cable openings face down .
3. Connect the heavy main cables, main battery switches and fuses as described in the
“visual” wiring diagram to the thruster, series/parallel switch box and batteries. Make sure
to label all cables in both ends to ensure correct connection points. Remember to t the
rubber seals around the cables and in the box. (See FIG.3 and FIG.4)
4. Check again that the main cable wiring in the system is correct !
5. Extend the included 2-lead wire coming out of the series/parallel switch box (grey and
black) and connect these to the lower connectors on the thrusters main solenoid contactor.
(See FIG.3 + FIG.5)
6. Install the control panel(s) as per the instructions. The panels should be connected directly
to the thruster as in a “normal” installation without a series/parallel switch box.
7. If you are installing a sternthruster, make sure to follow the instructions in the sternthruster
installation manual to move the electronic controlbox away from the thruster and seal the
thruster compartment from general bilge water. The electric installation of bow and stern
thrusters must be treated as separate thrusters in terms of electric wiring so that each
thruster must have its own series parallel box with all the connections and a seperate
Batt.2 and the 2-lead controlcable between the series parallel box and the thruster.
There is an example diagram (FIG.6) on page 7. You can also use seperate battery bank 1
for each thruster, remember the 12V charge feed as described.
NB! If you are installing both a bow and a sternthruster with series/parallel switch boxes the
Batt.1 bank can be common for both thrusters providing it has the necessary capacity
(minimum x 2,5) but there must be an individual Batt.2 for each thrusters. (see FIG. 6)
Minimum battery capacities
Batt.1 Batt.2 Slow fuse / main switch rating
SE170TC 600CCA din 600CCA din 400A for 10 minutes
SE210TC 750CCA din 750CCA din 550A for 10 minutes
SP240TC 800CCA din 800CCA din 600A for 10 minutes
- CCA din is the Cold Cranking Amps rating by the DIN standard.
If your battery is rated by other standards, you should use the following factors:
DIN = SAE & BCA / 1,9 (Example: rating is 800 CCA BCA = 421 CCA DIN) DIN = IEC / 1,3
REMEMBER!
Bigger and more powerful batteries and cables will increase the thrusters performance
as there will be less voltage drop to the thruster. The sizes mentioned in the manuals
are the minimum sizes and the larger, the better.
