ELECTRICAL INSTALLATION OF STERNTHRUSTER SYSTEMS
PS ! This is additional information especially for sternthruster installations, and the installation
manual for the thruster you are installing must be used complementary.

If a bow thruster is also installed, we strongly advice to use seperate battery banks for the two
thrusters to avoid extreme voltage drop if both thrusters were to be used at the same time, and to
ensure maximum performance.
Battery banks must have common minus!
Refer to the thruster manuals for advised battery capacity and cable sizes for each thruster.
If a single control panel other than Sidepower’s is to be used for both bow and stern thruster,
be sure it has a single positive connection from only one of the two thrusters to avoid current
leakage between the two battery banks. If you are installing the standard Sidepower dual
joystick panel this is already taken care of.
