9 CONTROL SYSTEM
Install a breaker/isolator in the supply wiring of the thruster control box on the boats’ main
electrical switchboard marked BOW THRUSTER:
This breaker/isolator should ideally be supplied from an independent battery bank, to the one
used for powering the thruster unit.

Thruster Battery Bank
(12/24V depending on thruster voltage, see "Power Connections")
NOTE: Thrusters which are equipped with a “thruster control box” can only be used with
Max Power’s range of control panels as shown in this manual.
The thruster controller can be supplied in either 12V or 24V, depending on the thruster
voltage.
The installer must protect the positive supply cable of the thrusters control box by means of a
fuse as indicated in the above drawing. The size of the supply wires (red & black) depends on
the length of the cable run, the voltage drop in these cables should not exceed 5% of the
nominal battery voltage.
For safety reasons and in order to benefit from all the functions provided by the thruster
controller, an electric battery isolator needs to be installed in the thruster motor’s positive
supply cable.
If an electric battery isolator is not used then simply seal-off the two grey wires coming out of
the control box. It is important to isolate the thruster motor power circuit by means of the
manual battery isolator after having left port & when the manoeuvre is finished, after docking.
Please refer to the drawing “Connection of Controller to Thruster Motor” in the back of this
manual for more detail on the wiring of the controller to the thruster unit.
