Electrical Installation - Simrad TP20 Manual

5.2 Electrical Installation

The Tillerpilot operates from a 12v DC supply. It is
supplied with a high quality six pin waterproof
connector ready fitted, which is used to supply the
power, NMEA and (where appropriate) Canbus
data. The mating 6-pin bulkhead socket is also
supplied with the unit.
The six pin bulkhead socket should be mounted in
a convenient position close to where the Tillerpilot
is to be fitted, and wired in accordance with Fig 5.4.
Important - If the vessel has more than one sepa-
rate battery bank, when connecting the Tillerpilot
to the power supply always ensure that the pilot
and all interfaced equipment - whether Canbus
or NMEA - are connected to the same battery
bank, even though they each have independent
connections to the switch panel. This is to avoid
a possible voltage drop between the interfaced
equipment which would render the equipment
inoperative.
* Mount the bulkhead socket on a vertical surface
to prevent standing water gathering around or in
the socket. Always fit the protective cap when the
pilot is not plugged in.
* Use a suitable gauge cable for the run from the
socket to the supply (see Fig 5.5).
* Connect to the vessel's switch panel via a 10 Amp
fuse or breaker.
* Do not fit other electronic or electrical equipment
to this cable, or "tap into" the supply from a near-
by cable - always wire each piece of equipment to
its own breaker in the switch panel.
* Ensure all wire ends are tinned, and any connec-
tions are well made. Poor contact will result in loss
of thrust from the Tillerpilot and slower speed of
response.
* If in any doubt, employ a qualified engineer to
install the equipment.
