Reverse Polarity Light
The red light indicates reverse polarity cur-
rent supplied to the panel. This situation will
cause the red light to illuminate. Additionally,
a relay attached to the main breaker will
automatically turn the main breaker off
whenever reverse polarity occurs. If reverse
polarity occurs, immediately turn off all cabin
AC breakers and dockside outlet breakers.
Disconnect the power cable from the dock-
side outlet and notify a qualified electrician
to check the dock side wiring.
AC Main Breaker
Protects the general distribution network.
This breaker is very sensitive. The resulting
power surge that occurs when connecting
the dockside cord may cause the main
breaker to trip. To avoid this surge, turn the
main breaker to "OFF" position before plug-
ging or unplugging the shore power cord.
Battery Charger
Supplies AC directly to the battery charger.
Outlets
Supplies AC to the outlet(s). AC electrical
outlets are provided with (GFCI’s) to help
protect against electric shock. Test outlets
periodically by pressing the test/reset but-
tons in the center of the faceplate to ensure
proper operation. GFCI outlets do not pro-
tect against short circuits and overloads.
This protection is done by the outlet break-
ers on the AC panel.
GFCI outlets do not provide 100% protection
from electric shock. Even though GFCI out-
lets protect by reducing exposure time from
line to ground shock hazards, it is still possi-
ble to receive an electric shock from defec-
tive appliances, power tools or misused
electrical equipment.
Accessory
Reserved for additional AC equipment.
4.7 Battery Charger Operation
The battery charger charges and maintains
the 12-volt batteries simultaneously when
activated. The battery charger is located on
the aft wall of the center console on C280,
S280 and C310 and under the aft seat on
the ST310. It is automatic and is equipped
with an ammeter to monitor charging. At
dockside, when the boat is connected to
shore power, the battery charger maintains
the charge on the house and engine batter-
ies. Refer to the battery charger manual for
more information.
The wires that supply DC charging current to
the batteries are protected by an internal
fuse in the battery charger and three circuit
breakers, one for each battery bank output
wire. The breakers protect the DC charging
circuit from the batteries to the charger. They
are located on the DC Main Distribution
Panel. Push to reset the breakers. The inter-
nal fuses in the charger protect the DC
charging circuit from the charger to the bat-
teries.
4.8 Shore Power Connection
Connecting Shore Power
If you suspect the shore power connection
system is faulty or damaged, have a quali-
fied marine electrician check the system.
Turn the AC main breaker to "OFF" position.
If the dockside outlet includes a disconnect
switch, turn it to "OFF."
! DANGER
ELECTROCUTION HAZARD
Exposure to high voltage will cause
death or serious injury. DO NOT
attempt to correct wiring yourself. DO
NOT swim in marinas or near boats
connected to shore power. Keep chil-
dren away from any electrical cables
or equipment and use grounded appli-
ances onboard only.
