Your yacht is equipped with an
transformer.
The boat's electrical system and
grounding conductor are not actually connected to
the dockside system. The Isolation Transformer
transfers power from the dockside electrical system
to the boat's electrical system by magnetic coupling.
This means there is no direct electrical connection
between the earth-grounded shore AC power and
boat AC power. Isolating the power this way has
several benefits which are listed below:
1. Eliminates shock hazards to people swimming
around the boat.
2. Prevents reverse polarity due to a miss-wired shore
power pedestal providing futher protection to people
onboard as well as sensitive AC appliances.
3. Prevents galvanic current corrosion due to the
direct connection to AC shore power.
REFER TO OWNER'S MANUAL PACKET FOR
INSTRUCTIONS AND WARRANTY INFORMATION.

The IsoBoost Transformer combines a shoreline
Isolation Transformer, described above, with a
voltage sensing and switching circuit providing the
ability to automatically increase the line voltage on
your boat, all in a single unit. The isolation
transformer completely isolates input power from
output power giving you an improved degree of
safety and preventing galvanic current corrosion
due to the direct connection to AC shore power.
The IsoBoost increases the boat's voltage when it
falls below 204 volts due to low shoreline voltage.
The IsoBoost gives you the reliability and assurance
that adequate voltage is provided for all the AC
equipment on the boat.

1. The output voltage is boosted (increased) by
15% if the suppied voltage is to low. This low
voltage commonly occurs when connecting to
marina power sources that are derived from a
208 volt system rather than from a 240 volt
system. The IsoBoost Transformer can extend
the useful life of many electrical components
installed on the boat.
2. Monitors the incoming voltage and alarms to
warn you that the shore voltage has dropped to
a level outside the boosting range. It will
automatically shut down under conditions of
extreme low voltage.
3. The remote indicator panel (installed at the main
distribution panel in the cabin) allows you to
monitor the operating status of your IsoBoost
Tranformer without having to go physically to
the engine room to look at it. Refer to IsoBoost
manual in owner's manual packet for detailed
instructions.
4. Boat system protection: if the boat's voltage
drops below 192 VAC for more than four
seconds, the IsoBoost output is turned off.
Power will not be supplied again until shore
)
voltage has increased by at least 20 VAC. If
the boat's voltage exceeds 260 VAC for five
seconds, the IsoBoost output is turned off. Refer
to IsoBoost manual in the owner's manual
packet for detailed instructions.
If the IsoBoost Transformer turns off for a prolonged
period of time, turn on the generator to supply AC
power. Follow generator operating instructions (See
Section 3 - Using Your Boat , page 3.8).
