1.1 Siting
Autohelm
The ST30 Speed may be installed above or below deck where it is:
• easily readable by the helmsman (normally viewed at eye level)
• protected from physical damage
• at least 230mm (9in) from a compass
• at least 500mm (20in) from radio receiving equipment
• accessible from behind for ease of installation and cable running
Note:
To prevent the build-up of moisture the instrument breathes through
the back cover. For this reason the instrument must be mounted where
the back cover is protected from direct water.
The rear case is fitted with a foam gasket to form a water-tight seal
between the instrument and the installation face.

1. Make sure the surface to which the instrument (1) is to be mounted is
smooth and flat.
2. Use the template (supplied) to mark the centres for the two fixing
holes and the instrument connector boss.
Note:
To allow protective covers to be fitted, adjacent instruments
should be sited not less than 6mm (0.24in) from each other (116mm
centre to centre min.).
3. Drill two 5mm (0.2in) diameter holes for the fixing studs (2).
4. Using a 60mm (2 3/8in) diameter cutter, drill a location hole for the
instrument connector boss.
5. Connect the power supply and transducer cables to the back of the
instrument (1) (see relevant installation sections).
6. Screw the two fixing studs (2) into the back of the instrument (1).

For stand-alone operation, use the 1 metre cable supplied with the
instrument.
1. Connect the moulded power supply plug to either SeaTalk connection
on the rear of the instrument and run the free end back to the
vesselÕs distribution panel.
2. Cut the power cable to length and connect the red wire to the positive
12V terminal and the screen to 0V. Protect with a 5A circuit breaker
or fuse.
1.4 Power supply (SeaTalk operation)
If the ST30 Speed is to be connected to an existing SeaTalk system use a
Standard SeaTalk Extension or Interface cable.
