Connecting the ADCU to Vessel Power
Short circuits may result in severe electrical shock or burns. Turn
off vessel power and test the circuit to ensure that no power is
present before connecting any power cables. Do NOT reapply
power until all system wiring is completed and all terminal
strip connectors are installed on the ADCU rear panel, as
described in "Connecting the Terminal Strip Connectors to the
ADCU" on page 38.
The TracVision G4 system requires an 11-16 VDC power input.
Since it does not have a dedicated power control (ON/OFF
switch), a quick-tripping circuit breaker or fuse should be
installed between vessel power and the ADCU. Circuit overload
protection should be rated for 5 amperes. For recommended
power cable specifications, refer to Table 2-2 on page 10.
If vessel power fluctuates widely or is noisy, a 12 VDC, 5-amp
AC/DC power supply or a wide-range DC/DC converter power
supply should be installed. Test the voltage and polarity before
making connections to vessel power.
Connect power to the green ADCU terminal strip connector as
shown in Figure 2-28. If the user-supplied power cable has a
drain or shielded wire, DO NOT connect the drain or shield to
either the ADCU or to ground.

Connecting the IRD Ground Wire
If you've routed an IRD ground wire to the ADCU (as
recommended in "Connecting the IRD Ground Wire" on page 28),
connect the wire to terminal 2 of the green ADCU terminal strip
connector (see Figure 2-28).

Before connecting the power cable,
turn off vessel power and test the
circuit to ensure that no power is
present.
Power supplied to the
TracVision G4 MUST NOT exceed
16 VDC or the TracVision power
supply will suffer serious damage!
