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-IP / CT45-IP 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:

≤

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.
Example:
Battery: Exide Maxxima900 12V
Capacity: 55 Ah
CCA: 800
