Introduction
roduct description
Welco e to the installation guide for the Ray arine rotary drive. This product is intended to
operate the boat’s steering echanis as part of a Ray arine autopilot syste . It is designed
for steering syste s that can be driven fro the hel position through a chain and sprocket
(for exa ple: cable and rod steering syste s).
The outstanding design of the Ray arine rotary drive unit provides s ooth, powerful
autopilot-controlled steering with quiet operation.
The ain parts of the drive are:
• a rugged electric otor, that drives a precision epicyclic gearbox via a high tensile drive
belt
• an electro agnetic clutch that trans its high torque loads without slipping

1. EMC installation guidelines
All Ray arine equip ent and accessories are designed to the best industry standards for use
in the recreational arine environ ent.
Their design and anufacture confor s to the appropriate Electro agnetic Co patibility
(EMC) standards, but correct installation is required to ensure that perfor ance is not
co pro ised. Although every effort has been taken to ensure that they will perfor under all
conditions, it is i portant to understand what factors could affect the operation of the
product.
The guidelines given here describe the conditions for opti u EMC perfor ance, but it is
recognized that it ay not be possible to eet all of these conditions in all situations. To
ensure the best possible conditions for EMC perfor ance within the constraints i posed by
any location, always ensure the axi u separation possible between different ite s of
electrical equip ent.
For optimum EMC perfor ance, it is reco ended that wherever possible:
• Ray arine equip ent and cables connected to it are:

• At least 3 ft (1 ) fro any equip ent trans itting or cables carrying radio signals
e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance should be
increased to 7 ft (2 ).
• More than 7 ft (2 ) fro the path of a radar bea . A radar bea can nor ally be
assu ed to spread 20 degrees above and below the radiating ele ent.
• The equip ent is supplied fro a separate battery fro that used for engine start. Volt-
age drops below 10 V, and starter otor transients, can cause the equip ent to reset. This
will not da age the equip ent, but ay cause the loss of so e infor ation and ay
change the operating ode.
• Ray arine specified cables are used. Cutting and rejoining these cables can co pro ise
EMC perfor ance and ust be avoided unless doing so is detailed in the installation
anual.
• If a suppression ferrite is attached to a cable, this ferrite should not be re oved. If the fer-
rite needs to be re oved during installation it ust be reasse bled in the sa e position.
Suppression ferrites
The following illustration shows typical cable suppression ferrites used with Ray arine
equip ent. Always use the ferrites supplied by Ray arine. This product has ferrites ounted
internally.
Figure 2: Typical suppression ferrites
Connections to other equipment
If your Ray arine equip ent is to be connected to other equip ent using a cable not
supplied by Ray arine, a suppression ferrite MUST always be attached to the cable near to
the Ray arine unit.

2. Mounting the drive
Mounting the drive involves four ain steps:
• securing the drive to the boat
• connecting the drive to the steering syste
• ensuring correct sprocket align ent and chain tension
• co pleting a steering check
Securing the drive
Mounting location
Before you secure the drive to your boat, you ust first check the suitability of the ounting
location.
•Structural strength:
• This drive produces a considerable a ount of force, so you ust ount it on a solid
structure (i.e. a substantial fra e e ber) in the boat. In so e cases you ay need to
build a special fra e to ount the drive unit.
• To prevent excess noise and vibration, do not attach this drive to any structures that
support cabins.
•Drive orientation:
• The drive can be ounted on a vertical or horizontal surface.
• If necessary, you can rotate the ounting foot through 90 degrees to provide a ore
convenient ounting position (as shown in Figure 6 ). To do this: re ove the four
screws securing the ounting foot to the drive unit, rotate the ounting foot, then
replace the screws.
• Additionally, the drive ay face either way as you can correct the steering direction by
reversing the polarity of the otor connections at the course co puter (see Figure 2 ).
•General position:
• Refer to the EMC installation guidelines ( page 9 )
• Make sure the drive will be accessible for future servicing.
CAUTION
Mounting location
Consult the Boat Manufacturer if you have any doubt about the strength or
suitability of the mounting location.
