5.2 Electrical installation
5.2.1 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 (Fig 5.5).
Caution
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 inter-
faced equipment, which would render the equipment inoper-
ative.
•
Mount the bulkhead socket on a vertical surface to prevent stand-
ing water gathering around or in the socket. Always fit the protec-
tive cap when the pilot is not plugged in.
• No power is supplied to or from the SimNet bus – the Tillerpilot
must always have its own dedicated power connection.
• Use a suitable gauge cable to run from switch panel to the socket
(see Fig 5.6).
• Connect to the vessel’s switch panel via a 10Amp fuse or breaker.
• Do not fit other electronic or electrical equipment to the supply
cable or “tap into” the supply from a nearby cable – always wire
each piece of equipment to its own breaker in the switch panel.
• Ensure all wire ends are tinned, and any connections 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.
