Grounding Requirements
Proper grounding of the antenna 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
antenna's control unit 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 antenna control unit's power plug. As an
alternative, you may run a separate ground wire from the antenna
equipment's chassis to ship's ground, or mount the equipment within
a grounded equipment rack.
Failure to ground the antenna 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.
You are responsible for the quality and safety of the system's
installation. Be sure that it meets these critical power and grounding
requirements.
