Connecting the Antenna Data/Power Cable
Connect the antenna data/power cable to the data/power
connector on the MCU’s rear panel (see Figure 2-16). Do not
overtighten; finger-tight is sufficient.
Connecting Vessel Power and the Ground Wires
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.
The TracVision G8 system requires a 9-36 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 MCU. Circuit overload
protection should be rated for 15 amperes. For recommended
power cable specifications, refer to Table 2-2 on page 22.
A power connector plug has been supplied in the kitpack to
make connecting power to the MCU a snap. To connect vessel
power and the ground wires, follow the steps below.
1. A large ferrite coil is supplied in the kitpack to help
reduce conducted emissions from the vessel power cable.
This ferrite coil needs to be installed for the system to
comply with CE standards. To install the ferrite coil, make
two loops in the vessel power cable and clamp the ferrite
coil around the loops (see Figure 2-17). The cable, with
both positive and negative wires, must pass through the
ferrite coil three times to be effective.

TracVision G8 Owner’s Manual - Guide to Technical Information
KVH recommends a 12 VDC
(5 amps) or a 24 VDC (2.5 amps)
power input to the TracVision G8
(supplying not less than 9 VDC at
the MCU). Power supplied to the
TracVision G8
MUST NOT
exceed
36 VDC or the TracVision power
supply will suffer serious damage!
Before connecting the power cable,
turn off vessel power and test the
circuit to ensure that no power is
present.
