SE170/250TC Ignition Protected thruster assembly 1.1 - 2010
• Explanation of electrical table
- All cable lengths are the total of + and - (to and from).
- Battery size is stated as minimum cold crank capacity, not Ah.
- Use slow fuse rated to hold stated Amp-Draw for min. 5 minutes.
* Cable size and main battery size when an extra bow battery with minimum the CCA mentioned as A is installed.
• It is important that you use a good cable size and batteries with a high cranking capacity to feed the thruster, because it is the actual
voltage at the motor while running the thruster that decides the output rpm of the motor and thereby the actual thrust. Please see the
list below for advised min. sizes of cables and batteries. You can of course use larger cables for even better results.
• A main switch (*C) that can take the load without noticable voltage drop must be installed in the main positive lead so the power
for the thruster can be turned off independently of the rest of the system when not on board or in emergencies. This should be placed
in an easily accessible place and the boats instructions should include information that this should be turned off like the other main
switches of the boat.
• We also advice to install a fuse (*D) in the positive lead for protection agains short circuiting of the main cables. This fuse should be
of a adequate quality which normally means that it is physically large as these have less voltage drop than the simple / small ones. It
should be of the slow type and sized to take the amperage draw for atleast 5 minutes.
• Remember to use ignition protected fuses and switches if tted in areas that require this feature.
• A circuit breaker can be used instead of the fuse and main power switch as long as the functionality is the same.
• The cable ends must be tted with terminals and these must be well isolated against contact with anything but the proper connection
point.
• If the main switch and fuse are installed in the same gas area they also have to be ignition protected.
• The negative / minus cable connects to the (-) terminal. Bolt M10. Tighten with 25 Nm / 18,43 lb/ft.
• The positive / plus cable connects to the "+" terminal. Bolt M10. Tighten with 25 Nm / 18,43 lb/ft.

• Übersicht:
- Leitungslängen beziehen sich auf die Gesamtlänge von + und -
- Batterieangabe ist min. Kaltstartkapazität, nicht Ah.
- Sicherung: träge Ausführung; angeg. Stomverbrauch min. 5 Min.
* Kabel- und Batteriegröße, falls eine zusätzliche Batterie, mit min.
der Kaltstartkapazität (mit A angegeben), im Bug installiert ist.
• Da die am laufenden Motor anliegende Spannung die Umdre-
hungszahl und damit die Leistungskraft bestimmt, sind Kabel mit
ausreichendem Querschnitt und Batterien mit hoher Strom-
kapazität zu verwenden. Bitte die unten angegebenen Mindest-
größen für Kabelquerschnitt und Batterien berücksichtigen.
Natürlich können für noch bessere Leistung überdimensionierte
Bauteile verwendet werden.
• Auf der positiver Hauptseite muß ein Hauptschalter (*C) mon-tiert
werden, der die Leistung ohne größeren Spannungsverlust
weiterleitet. Damit kann die Spannung für den Thruster in Not-
fällen abgeschaltet werden, ohne die übrige Bordelektrik zu be-
einflussen. Dieser sollte an einer leicht zugänglichen Stelle pla-ziert
sein und die Anleitung darauf hinweisen, daß dieser wie die andere
Bordelektrik bei Nichtbetrieb abgeschaltet werden sollte.
• Zum Schutz gegen Kurzschlüsse empfehlen wir, in der positiven
Leitung eine Sicherung (*D) zu installieren. Es sollte eine
Qualitätssicherung von ausreichender Größe verwendet werden.
Die Sicherung sollte in "träger" Ausführung sein und die
angegebene Amperezahl mindestens 5 Minuten aushalten.
• Statt Sicherung und Hauptschalter kann ein Sicherungsautomat
verwendet werden, falls die gleiche Funktionalität gewährleistet ist.
• Die Leitungsenden müssen so mit Kabelschuhen versehen und
isoliert sein, daß sie nur mit dem Terminal Verbindung haben.
• Die Kabelschuhe müssen korrekt angezogen werden. Die innere
Mutter sichern (Fig. 2). Anzugsmoment max. 15 Nm / 11 lb/ft.
Das Minus-Kabel (Negativ) (*A) am A1 (-) Terminal anschließen.
Das Plus-Kabel (Positiv) (*B) am "+" Terminal anschließen
SP 75/95/125: ø10mm Bolzen. Anzugsmoment: 15 Nm / 11 lb/ft.

bolt. Tighten with 15 Nm/11lb/ft.
NB! Very important to check the following with mainswitch
in off position:
After all electrical connections have been completed check withan
ohm meter that there is no electrical connection between electro-
motor body and positive terminal on the motor and between the
electromotor body and the negative (A1) terminal on the motor. If
you feel unsure on how to perform this check, contact skilled
personnel for guidance.
