f) When finished with the final adjustments, fix the alloy plate bracket by bolting through
the GRP turbine in addition to the cable clamps.
IMPORTANT: Please keep in mind that the power supply to up/down motors is not
automatically interrupted if the proximity switches do not detect the position detectors. Care
must therefore be taken to remove ones finger from up or down button as soon as the unit
blocks in fully up or fully down position when closing plate adjustments are done and if
position detectors are not adjusted yet.

4. ELECTRICAL INSTALLATION
4.1 GENERAL:
It is important that a qualified marine electrician does the electrical installation, since an
incorrect electrical installation will result in the rapid deterioration and/or failure of the unit.
All electrical components (thruster motor, relay, electronic control box, ect…) should be
installed in dry and ventilated areas.
Under no circumstances should any inflammable products be stored next to the electrical
components of the thruster.
When choosing cable sizes and the battery bank size and type, special care should be given
to voltage drops, since excessive voltage drops will cause premature failure of motors and
relay contacts.
Great care should be taken to correctly tighten all electrical connections.
Installation Advise: In order to make sure that VIP is
raising and lowering smoothly and when closing plate
adjustments are made, one can do the following:
a) Connect 12/24V (depending on thruster voltage)
directly to the two up/down motors and simply
reverse the polarity to change direction
(raise/lower).
It is important to install a 10A fuse in the
positive cable and to keep in mind that wires
need to be disconnected as soon as the up or
down position is reached or as soon as the unit
blocks, to avoid damaging the up/down motors.
b) If the unit blocks before reaching the up/down
position or if the unit vibrates excessively when
going up/down one needs to adjust the two
adjustment nuts to ensure the unit is completely
vertical to its base.
