Installing the TP22 and TP32
The Tillerpilot operates from a 12 V DC supply. The waterproof
plug fitted to the Tillerpilot is used to supply the power, SimNet
and NMEA data. The bulkhead socket should be mounted in a
convenient position, close to where the Tillerpilot is to be fitted, and
wired as shown.

Warning: If the vessel has more than one separate battery
bank, when connecting the Tillerpilot to the power supply, always
ensure that the pilot and all interfaced equipment—whether
SimNet or NMEA—are connected to the same battery bank, even
if 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
