‣ Terminals must be correctly clamped to motor
studs. Use a pair of spanners - the one nearest
motor to stop rotation of the stud.
‣ Spanner sizes are 13 mm.
‣ Tighten the bolts to 20 Nm (15 lbs.ft).
‣ Correct installation. Supplied cable boots are used
and no bare wires exposed (Fig 7.2.1).
‣ Live wire exposed! (Fig. 7.2.2). Correct the cable
installation to match (Fig 7.2.1).
‣ Terminal or motor is damaged. Contact Lewmar
Limited (Fig 7.2.3).
‣ Crimp inverted and is touching motor! (Fig 7.24).
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 20 m (66 ft) of cable with a model VRTT125 thruster would need 70 mm2 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 in line fuse fitted.
‣ The cables should be terminated with a ring terminal corresponding to the motor studs, 8 mm (5/16”) for
RT140. It is important that this termination is secure so that the high current is transferred to the motor
efficiently. The minimum voltage at motor when running should be 10V for 12V units.
‣ Ensure the insulating boots, supplied with the unit, are correctly fitted.
NOTE: If very large cables are used discard supplied boots and fit appropriate sized ones.
7 - Installation of electric motor
7.2 Battery cable connections
7.3 Correct cable sizes
DO NOT overtighten electric motor
terminal nuts.
⚠ 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.
