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 happening,
keep an open-ended spanner
on nut 1 while screwing on
bolt 2, without rotating this
spanner.
The torque for nut 2 is a maxi-
mum 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 75 kgf, ø 185 mm
Fit the control cable
between the bow
thruster and the con-
trol panel through
the vessel and con-
nect the jack con-
nections together.
If it is necessary to
cut the intermediate
cable and reconnect
it take care to ensure
the correct colours are connected 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 move-
ment.
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.
