Thruster Electrical Installation

!
Please refer to the graphic for special considerations relating to your model
!
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 flange and the positive terminal on the motor
2. electro-motor flange 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. Connect the battery supply to the control unit (PPC).
- Install a main manual/ automatic switch from the positive lead terminal on the battery PPC unit). The main switch must be accessible to turn
off the thruster independently from the rest of the electrical operation of the vessel when not on-board or in emergencies.
(NB: It is advised
to install a fuse on the positive cable for protection against short-circuiting of the main cables. The fuse should ensure no voltage
decrease, slow-blow and sized to take the amperage draw for at least 5 minutes.)
- A circuit breaker can be used instead of the fuse and main power switch If the functionality is the same.
(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.

IMPORTANT
The Proportional Power Controller is a bulkhead (wall)
mounted unit and must be installed in a dry and
well-ventilated compartment. The unit also requires a
200mm minimum head clearance, 150mm minimum
bottom clearance and a 100mm minimum clearance
surrounding its remaining outer casing.
Hold in place

Do NOT use washers between lugs, this
causes overheating and fire. Spring
