KVH Industries TracVision 4 - Manual (Page 28)

Connecting the Switchplate 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.
The TracVision 4 system requires an 11-16 VDC power input. A
quick-tripping circuit breaker or fuse should be installed between
the switchplate and vessel power. Circuit overload protection
should be rated for 5 amperes. 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.
Run a power cable from vessel power through the panel cutout
and connect it to the switchplate as shown in Figure 2-15. For
recommended power cable specifications, refer to Table 2-2 on page 10.
Connecting the IRD Ground Wire(s)
Find each IRD ground wire where it comes through the panel
cutout made earlier. Connect the IRD ground wire(s) to the
ground connector on the switchplate (see Figure 2-15).
