The installation is simple and you can do it yourself.
1. Mounting the display
Install the display where it is easy to reach. The front cover is
waterproof. The back cover with its electrical connections must be protected
from water. An optimum place would be e.g. the bulkhead beside the companionway
or the coaming compartment in the cockpit. Please allow at least
a distance of 6mm to adjacent instruments, so you can fit their sun covers.
You must fit a 12 A fuse to the 12 V power supply.
2. Mounting the compass sensor
The compass is primarily designed for below deck, bulkhead mounting.
On steel-hulled boats you must mount it above deck (e.g.the mast)
Recommended location for non-steel hulls
On steel-hulled boats the compass must be mounted at least 1,2 m above the steel deck or the wheelhouse.
You have to mount the compass on a vertical bulkhead in every direction,with the cables exiting at the base.
Connect the cable to the control unit
3. Mounting the control unit
Hold the drive to the spokes with the arrow at the top. So you can see which spokes you need. The wheel drive will fit 3, 4, 5, 6, 7 ot 8 spoke wheels.
Now you can drill the spoke clamp holes.
Secure the wheel drive to the wheel and fit the cover back onto the wheel drive. Now you can fit the ring from behind to the spokes with the spoke clamps. The inserts are suitable for 12mm and 16mm diameter spokes.
Fit the wheel onto the pedestal with the pedestal bracket and cut
this into lenght.
Connect the steering cable to the motor.
Route the cable to the control unit.
Connect the cable.
