KVH Industries TracPhone V11 Installation Manual page 26

12 Continued
Once you understand the requirements listed on
page 24, 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 AC power cords to the
CommBox-ACU and modem (see Figure 46).
c. Connect the supplied ground wire from the
ground screw on the CommBox-ACU rear
panel to ship's ground.
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 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.
d. Using tie-wraps, secure all wires to the strain-
relief bracket at the back of the CommBox-
ACU and modem. Leave enough slack for
easy serviceability.
e. Plug the CommBox-ACU and modem power
cords into the vessel's 100-240 VAC supply.
f. Connect the antenna's AC power cable to the
vessel's 100-240 VAC supply via a marine-
grade circuit breaker (or equivalent) that
complies with all applicable electrical codes
and safety standards. If the breaker is not
located 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.
