IMPORTANT
Do NOT use washers between lugs, this causes
overheating and fire. Spring washers must be placed in the
outer position before tightening the nut.
Hold in place for

Thruster Electrical Installation
EN
WARNING
Check the following with the main switch is set to off :
After all electrical connections have been completed check with an ohm meter that there is no electrical connection between
1. electro-motor fl ange and the positive terminal on the motor
2. electro-motor fl ange and the battery negative terminal on the motor
If unsure contact skilled personnel.
1. Information of electrical table.
see next page
- All power cable lengths represent the total length of the combined (+) and (-) cables.
- Battery capacity is stated as minimum cold crank capacity, (CCA).
- Use slow blow rated fuses to hold stated Amp-Draw for min. 5 minutes.
- Consider the AMP hours (Ah) for your specifi c duty cycle.
2. Use appropriate sized cables and batteries with high cranking capacity to feed the thruster. The actual voltage at the motor while running the
thruster decides the motors output RPM and thrust. Use larger cables and stronger batteries for better results.
- See electrical specifi cations for advised minimum cables and batteries (CCA).
3. Install the main switch as close to the battery as possible and ensure the main positive lead can take loads without noticeable voltage drop.
- Ensure the main switch (battery isolator) can be turned off independently and manually when not on board or in emergencies.
- Ensure it is easily accessible and update instructions that this should be turned off like the boat’s other main switches.
It is advised to install a fuse in the positive lead for protection against short-circuiting.
- Ensure a slow type and appropriately sized to take the amperage draw for at least 5 minutes.
(NB: For Ignition Protected installations remember to use ignition protected fuses and switches if fi tted in areas that require this feature.
Ensure to follow your national regulations)
5. Cable lugs must have adequate electrical and mechanical isolation and fi tted with cable lug covers.
6. Fasten cables to the required torque.
