SE 50/140S ignition protected thruster assembly
version 1.0.0 - 2017
•
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 noticeable 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 against 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 at least 5 minutes.
•
Remember to use ignition protected fuses and switches if fitted 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 fitted 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 20 Nm / 14.75 lb/ft.
•
The positive / plus cable connects to the "+" terminal. Bolt M10. Tighten with 20 Nm / 14.75 lb/ft.
Place the included red protection cap firmly on the terminal bolt, as shown in illustration above.

Battery & cable recommendations:
Minimum and recommended cable dimensions can be identical due to safety margins and cable heat considerations for short cable lenghts.

Tegninger for å illustrere batterikabel-lengder både for std truster og for proporsjonaldrift av
truster.
Har benyttet *C og *D som tidligere i manualer.Burde kanskje vært forklart at det er summen av
lengden for alle batt.kablene som gjelder for kabeltabellen.
Det bør stå en anbefaling av vår automatiske hovedstrømbryter i manualteksten.

NB! Very important to check the following with mainswitch in off position:
After all electrical connections have been completed, check with an ohm meter that there is no electrical connection between electro
motor flange and positive terminal on the motor and between the electro motor flange and the negative (battery -) terminal on the motor.
If you feel unsure on how to perform this check, contact skilled personnel for guidance.
