Lewmar V1-6 Windlass ref 65001201 iss.8 | 11
5. Electrical wiring
5.1 Electric cable selection
Plan the installation to suit the controls and give the operator a full view of the windlass. The wiring system
should be of the fully insulated type, which avoids possible electrolytic corrosion problems. We recommend the
use of type III stranded, tinned copper wire with copper crimp terminals. Most modern installations are negative
return (negative ground) but polarity should be checked.
Overload protection, in the form of the circuit breaker/fuse supplied, must be built into the windlass wiring
circuit.
DO NOT confuse cable length
with the length of the vessel
NOTE: The circuit breaker should be positioned close to the battery in a dry, readily accessible place.
WARNING!
The breaker must be manually reset should an overload occur that causes it to trip to the off position.
If you are not sure you understand these guidelines, seek professional help. Ensure that the installation
complies with USCG, ABYC, NMMA or other local regulations.
5.2 Wiring
Lewmar recommends the installer source and install cable that meets the requirements of the standards and
regulations relevant to the installation and codes of practice. The cable table gives recommended cable sizes
based on total length of cable required, from the battery, following the route of the cables.
Windlass performance is directly related to cable size and length. Voltage drop over the complete wiring run
must not exceed 10%.
When wiring Lewmar electric motor into the ship’s
electrical system the following caution must be taken.
When tightening the front nut hold the back nut with
a separate wrench to make sure the back nut does
not turn. If the back nut turns, serious damage will
occur, voiding Lewmar’s warranty on the electric
motor.
5.3 Electric motor terminal connections
DO NOT overtighten electric motor
terminal nuts.
