KVH Industries TracPhone V3-HTS Installation Manual page 20

11 Continued
Once you have read and understand the
requirements described on page 18, follow these
steps to connect power to the TracPhone system.
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 point on the ICM rear panel to ship's
ground (see Figure 30).
c. Connect the supplied AC power cord to the
ICM.
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.
d. Using tie-wraps, secure all wires to the strain-
relief bracket at the back of the ICM (see
Figure 31). Leave enough slack for easy
serviceability.
e. Double-check all of your wiring.
f. Plug the ICM power cord into the vessel's 100-
240 VAC supply.
NOTE: Consider installing an uninterruptible power
supply (UPS) to avoid service interruptions during
power outages and transitions to/from shore power.
