Follow these steps to connect power.
a.
Before you begin, disconnect vessel power
and be sure the vessel is properly grounded
in accordance with marine standards.
b.
Connect the supplied ground wire from the
ground screw on the ICM rear panel to ship’s
c.
Connect the supplied AC power cord to the
ICM.
d.
Using tie-wraps, secure all cables to the
strain-relief bracket at the back of the ICM
(see Figure 47). Leave enough slack for easy
serviceability.
e.
Plug the ICM power cord into the vessel’s
100-240 VAC supply.
f.
Connect the antenna’s power cable to the
vessel’s 100-240 VAC supply via a marine-
grade circuit breaker (or equivalent) that
complies with applicable electrical codes and
safety standards. If the breaker is not within
sight of the antenna, it must be able to be
locked open.
Be sure to connect the cable’s
ground wire to the ship’s common ground.
NOTE:
Consider installing an uninterruptible power
supply (UPS) to avoid service interruptions during
power outages and transitions to/from shore power.
WARNING
Failure to ground the TracPhone 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 2 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.
