Connect Power

Before connecting power, be sure the vessel is
properly grounded in accordance with marine
standards.
Grounding Requirements
Proper grounding of the TracVision system to
ship's ground is critically important, as it protects
the equipment from electrostatic discharges (ESD).
Follow these steps to ground the system.
a. Connect the hoop of the grounding wire
(supplied in kit) to the "Ground" screw on the
rear panel of the TV-Hub. Connect the other
end to ship's ground.
b. Connect grounding blocks in-line with all of
the RF cables. Attach a ground wire from each
grounding block to ship's ground. Then mount
each grounding block using the two supplied
#6 screws (see Figure 35).
WARNING
Failure to ground the TracVision system
properly to the vessel's ground will cause an
unsafe floating ground condition, risking
damage to the antenna and electric shock,
potentially resulting in DEATH. In a
floating ground condition, the difference
between the equipment's chassis ground and
the vessel's ground can measure well over
100 volts, when it normally should not
exceed 2 volts. Therefore, always measure the
difference in potential between chassis
ground and the vessel's ground to make
certain there is no dangerous floating ground
condition.
