Refer to the drawing in Appendix B for help with
identifying components and installing them correctly.
 Remove windlass from its packing case.
 Make sure the mounting area on the deck is
properly prepared, as per step 3 above and is
clean.
 Clean the underside of the windlass case.
 Use sealant/bedding compound between deck,
pad/gasket and the windlass case and lower the
windlass, aligning the mounting holes in the case
with the pre drilled mounting holes in the deck
and bed the windlass down.
 Make sure that the four insulating bushes are in
place in the mounting holes in the case.
 Stainless steel washers should be used under the
head of the mounting bolts to spread the load on
the insulating bushes.
 Apply a little sealing compound to the four
mounting bolts and feed the bolts down through
the bushes in the case and deck.
 From the underside of the deck offer up the clamp
plates or large washers and fix in place with the
nuts.
 The chainpipes should now be fitted. If the deck
is steel or aluminium the chainpipe and fastenings
also must be insulated from the deck.
chainpipes must be through bolted using 316
stainless steel countersunk screws with the nuts
under deck backed up with large stainless steel
washers. When fixing, ensure that the stripper
arms are aligned squarely in the groove of the
chainwheel with the bevelled end in close
proximity to but clear of the root of the groove.
The chain must pass over the wheel and cleanly
through the pipe without fouling on the stripper.

POWER CONECTIONS TO DC MOTOR
The main power system is a two cable, ungrounded,
fully insulated, negative return system. The motor is
of the isolated earth type. This system is selected to
minimise electrolytic corrosion problems.
The DC motor has three power terminals, marked
"F1", "-" and "F2". Terminal "-" should be connected
directly to "-" terminal on the battery, see wiring
schematic in Appendix C. Terminal "F1" and "F2"
should be connected to solenoids. Depending on the
desired direction of rotation, these terminals may
need to be swapped around.
See Table 2.1 to select the appropriate cable size for
power supply. The recommendation assumes that
the cable insulation has a minimum temperature
rating of 90°C and sizes allow for a maximum 10%
voltage drop over the total length.
Cable lengths given are from the battery terminal to
the terminal on the motor, via the solenoid box, and
then back to the battery.
Where a portion of cable runs through the engine
room, a size increase should be made as indicated.
After connecting the cables, spray all terminals with
anti-corrosive waterproof coating, "CRC 3013 Soft
!
Extra care should be exercised when
handling polished parts to avoid any damage
to polished surfaces.
!
Tighten the nuts progressively and evenly.
DO NOT USE POWER TOOLS.
Do not over tighten. Ensure installation is
firm.
The
!
When tightening the cables to the motor,
ensure the lower nut is secure against
turning when tightening the upper nut. This
will prevent damage occurring within the
motor.
