Electrical installation

Make sure that no other electrical parts come loose
when connecting the electric cables.
Check all electrical connections after 14 days. Electrical
parts (such as bolts and nuts) may come loose as a
result of fluctuations in temperature.
Check that the voltage, recorded on the motor type plate, is in
agreement with the vessel's circuit voltage. Position the battery
or batteries as close as possible to the bow thruster; the main
power supply cables can then be short, which reduces the volt-
age drop as much as possible.
Connect the main power supply cables.
N.B.!
Be careful not to rotate
the bolt and nut 1 while
connecting the cables.
To prevent this hap-
pening, keep an open-
ended spanner on nut
1 while screwing on bolt
2, without rotating this
spanner.
The torque for nut 2 is a
maximum of 11 Nm.
Fit the control panel next to the steering position. There must be
at least 50 mm space behind the panel.
Operation manual and installation instructions Bow thruster 125 kgf, ø 250 mm
Fit the control cable
between the bow thrust-
er and the control panel
through the vessel and
connect the jack connec-
tions together.
If it is necessary to cut
the intermediate cable
and reconnect it take
care to ensure the cor-
rect colours are connect-
ed together. N.B: The
colours of the wire cores
in the intermediate cable
may differ from the wire
core colours as used on the bow thruster motor and on the
control panel!
A time-delay (BPTD) can be
fitted between the bow thrust-
er motor and the operating
panel switch. This allows the
electric motor to come to a
stop when a switch is made
from port to starboard (or vice-
versa) in one movement.
If there are two steering positions, the second control panel can
be connected to the first one.

If it is found during test running that the thrust direction does not
correspond with the direction switch on the control panel then
the blue (no. 1) and the white (no. 4) wires on the relay must be
interchanged.
Do NOT test the bow thruster while the ship is out of
water, unless you are certain that everyone is at a safe
distance from the thrust tube.
Never allow the bow thruster to run for longer than 5
seconds with the ship out of water.
