Grounding Requirements
Proper grounding of the TracVision system to
ship's ground is critically important, as it protects
the equipment from lightning and electrostatic
discharges (ESD). Failure to ground the chassis of
the ACU risks damage to the antenna and electric
shock.
In a standard installation with a connection to
single-phase AC power, the antenna system is
normally connected to ship's ground through the
ground wire of the ACU's power plug. As an
alternative, you may run a separate ground wire
from the TracVision equipment's chassis to ship's
ground, or mount the equipment within a
grounded equipment rack.
WARNING
Failure to ground the TracVision system
properly to ship'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 ship's ground can measure well over
100 volts, when it normally should not
exceed 25 volts. Therefore, always measure
the difference in potential between chassis
ground and ship's ground to make certain
that there is no dangerous floating ground
condition, even if the ground pin of the
vessel's AC power plug appears to be intact.
