Electric/Hydraulic TT Thruster 140 - 300

2.6 Correct cable sizes
NOTE: Cable length is total from
battery to thruster and back.
• Example: Measure the total cable run
from the battery to thruster and back
in metres. Grey area on the table shows
a total of 28 m (92 ft) of cable with a
model 250 8.0 kW thruster would need
95 mm CSA (000 AWG) cable.
• Battery crank capacity should be at
least equal to the thruster current.
• Main power cables should be run from
the batteries and must have an inline
fuse fi tted.
• The cables should be terminated with
a ring terminal corresponding to the
motor studs, 8 mm (
5
/
16
”) for 140TT
and 10 mm (
3
/
8
”) for 185TT, 250TT
and 300TT. It is important that this
termination is secure so that the high
current is transferred to the motor
effi ciently. The minimum voltage at
motor when running should be 10 V
for 12 V and 21 V for 24 V units.
• Ensure the insulating boots, supplied
with the unit, are correctly fi tted.
NOTE: If very large cables are
used discard supplied boots
and fi t appropriate sized ones.

Incorrect installation of battery cables
or damage to connection studs may
result in a short to the thruster body.
Use the examples above to check for
a correct installation on both +V and
-V battery connections.
The installation MUST have a battery
switch that is switched off whilst the
thruster is not in use or the boat is
unoccupied.
