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 mandatory for electromagnetic
compatibility (EMC) and safety regulatory
compliance. It protects the equipment from
electrostatic discharges (ESD) and prevents
interference with other electronic equipment.
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 common ground.
b.
If multiple RF cables are connected to the
antenna, connect one or two grounding
blocks in-line with all of the RF cables (a
second grounding block is needed for RF3
and RF4). Attach a ground wire from each
grounding block to ship’s common ground.
Then mount each grounding block using the
two supplied #6 screws (see Figure 44).
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 that there is no dangerous floating
ground condition.
The TV-Hub and any grounding blocks must
be connected to the ship’s common ground to
maintain the same electrical ground potential.
