Manual CT60-IP & CT80-IP April 2009

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 either 13.8V or 25.4V.
The performance data of the CT60-IP / CT80-IP is measured with an approx.
consumption of 400A and 11V (12V) or 280A and 22V (24V) 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:
Cable lengths CT60-IP / CT80-IP 12V CT60-IP / CT80-IP 24V
L ≤ 5 m (2,5 x 2) 50mm² 35mm²
5< L ≤ 10 m (5 x 2) 70mm² 50mm²
10 < L ≤ 15 m (7,5 x 2) 95mm² 70mm²
15< L ≤ 20 m (10 x 2) 120mm² 95mm²
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.
Thruster Maximum Amperage Max Power Fuse size
CT60-IP / 12V 330A 160A
CT60-IP / 24V 180A 125A
CT80-IP / 12V 360A 200A
CT80-IP / 24V 200A 125A
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
