•Place the mounting template on the deck or mounting pad in the desired position for the windlass and hold it in place using adhesive tape.

•NOTE: Check the scale of the template matches the winch.

for the mounting studs. With a 65 mm (21/2”) diameter hole

•Next, using the wrench on the flats, tighten the studs until they bottom out in their holes. Do this to each of the studs in turn.

To achieve the best performance and to safeguard your electrical system it is essential that any electrical windlass be fitted with sufficiently large diameter cable to cope with the current draw imposed upon it and to keep the voltage drop within acceptable limits. In any circumstance voltage drop due entirely to cable resistance should not exceed 10%.

The following table gives recommended cable sizes. The recommendations are based on total length of cable required, from the battery, following the route of the cables.

•Total length of cable run is from the battery to the windlass, and from the windlass back to the battery.

DO NOT confuse cable Length with the length of the vessel!

•In Multi Station installations 14 AWG wire (1.5 mm² cross sectional area, 21/0.30 PVC covered) is used to connect the switches to the reversing control box.

Plan the installation to suit the controls and give the operator a full view of the windlass. The wiring system should be of the two cable fully insulated return 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. If necessary add a grounding strap between the mounting studs and an earthing point.

•NOTE: If a Contactor is used in a V700 installation, the Contactor must be sited in a dry location.

DO NOT install the contactor in the anchor locker.

If a contactor is installed in an anchor locker it is exposed to harsh conditions it is not designed to withstand. Furthermore this type of installation will void your warranty.

Overload protection, in the form of the circuit breaker/isolator supplied, must be built into the windlass wiring circuit. This protects the wiring and prevents undue damage to the windlass motor, in the event of its being stalled by an excessive load in service.

It is advisable to site the circuit breaker/isolator in a dry, readily accessible place. The Breaker/ Isolator supplied must be manually reset should an overload occur that causes it to trip to the off position.

•NOTE: Crimp terminals should be used on all wire ends wherever possible for good electrical contacts.

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.

saw, make the hole for the rode to pass throughwith a 115

mm (41/2”) diameter hole saw, make a hole for the motor

gearbox to pass through.

When all the holes have been made, remove the template. To help avoid water absorption by the deck, apply an appropriate marine sealant to the freshly cut hole edges.

•Fully screw the three mounting studs into the base of the windlass. This can be done, quite simply, using the multi-tool wrench supplied. Screw the studs into the base finger tight, with the flats towards the base as shown (Fig 1.6-5).

•Place the base mat in position on the deck, optionally, apply a suitable sealant to the base of the windlass, any mounting pad or around the studs.

DO NOT use a permanent adhesive/sealant, e.g., 5200

As a rule of thumb, if the flats on the studs are visible below deck, the deck and/or any packing is likely to be too thin to offer adequate support when the windlass is under load.

•NOTE: If using silicone or other rubbery type sealant, it is advisable to allow curing of the sealant before final tightening of the mounting nuts. Trim the studs back to 6 mm (1/4”) below the fully tightened nuts.

2.3 Control switch installation

Follow the mounting instructions supplied with the switch. Remember, in a Multi Station installation all switches must be wired in a parallel circuit.
