SE80/185T & SE100/185T Ignition Protected thruster assembly
1.0 - 2007
•
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 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 25 Nm / 18,43 lb/ft.
•
The positive / plus cable connects to the "+" terminal. Bolt M10. Tighten with 25 Nm / 18,43 lb/ft.

SP55S2i ignition protected thruster assembly
1.1 - 2006
•
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 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 25 Nm / 18,43 lb/ft.
•
The positive / plus cable connects to the "+" terminal. Bolt M10. Tighten with 25 Nm / 18,43 lb/ft.
