Power supply: The PILOT 3300 system requires two power supplies, both nominally 12 V DC:
The power supplies require one or two switches and fuses or circuit breakers (see section 3-4).
Steering drive: The PILOT 3300 system can power a hydraulic pump, constantly running pump set, hydraulic
linear drive or mechanical drive rated at 12 V DC and up to 20 A.
Rudder linkage: To link rudder to rudder feedback unit (see section 3-5).
For wiring, see Select Wire Table in section 3-4-2.
External beepers or lights (optional ): The external output is switched to ground, 30 V DC and 250 mA
maximum. If the beepers and lights require more than 250 mA total, fit a relay.
Other marine instruments (optional): Wind, speed or GPS instruments can be connected (see section 1-2).
Other parts: For systems of several instruments, wiring and connectors are required. Northstar junction boxes
can simplify wiring several Northstar instruments together (see section 1-2 or the NavBus Installation and
Reference manual).
Coupling connectors and 10 m (33 ft) extension cables are available to extend the rudder feedback unit,
compass or gyro cables. Do not fit more than one extension cable to each unit.
For more information, consult your Northstar dealer.
