Ensure that all electrical connections are correctly tightened. 

 

Under no circumstances should any flammable products be stored next to the 
electrical components of the thruster. 

 

 

It is essential to install a manual battery isolator and if possible an electric 

battery isolator at the base of the thruster motor power line. 

When using a manual battery isolator it must be visible, clearly marked & easily 
accessible. 
 

Thruster motor power supply: 

These values are given as an indication, assuming that the batteries are charged at 
100% and in charge, that is 13.8V. 
 
The performance data of the CT35 / CT45 is measured with an approx. consumption of 
250 Amps and approx. 11V at the motor’s connections. 
 
Please refer to the characteristics given by the manufacturer of the batteries that will be 
used

 (see section 9 “Batteries”)

 

Power wiring:  

Measure the shortest and most direct route possible between the battery(ies) and the 
electric motor; remembering to allow for both “positive 

and

 negative” cables. 

 

Recommended cable sections:

 15 m (7,5 x 2)

 20 m (10 x 2) 

120 mm² 

 

For all connections, use appropriate terminals for the cable sections chosen. 
It is possible to reduce the cable section to facilitate easy connection but 

only over a 

short distance.  

In this case

appropriated crimp fittings should be used at the 

connections. 
 

Please consult the "Electrical installation" diagram p. 11 for more information 

 
8. MAIN 

POWER 

FUSE 

 

Fuse sizes for overcurrent protection are to be determined on the basis of the cable 
sections in the circuit and NOT the amperage drawn by the appliance (thruster motor) in 
the circuit.

9. BATTERIES 

 

Thrusters are high amperage consumers with instantaneous demands, thus, we 
recommend you use maintenance-free “starting” type batteries, with high CCA outputs. 

For example: Exide Maxxima 900, 12V, capacity 55Ah / starting current 800CCA.
