10.1 Operaon of Standard Equipment
10.1.1 Baery Layout and Management
Your 280DC-X is equipped with three baeries, which are located in the a starboard bilge area. A cranking
baery is installed on each side, and a dedicated house baery is installed in the center. Wire leads run
through the hull harness to the baery management panel which is below the helm seat. See secon 6.5
thru 6.6.4 for informaon regarding the operaon of this panel. The engine cranking leads run a, through a
hull rigging tube, from the management panel to a posive stud mounted on the bulkhead in each a rigging
compartment. The negave engine leads are connected to the common baery ground using a negave buss
also located in the a rigging compartment.
The house baery provides the power for a majority of your DC accessories. The main baery lead runs to
the “HOUSE” switch on the baery management panel. From there current is routed to the dash and circuit
breaker through the 80 amp “DC Main” breaker located in the center of the baery management panel.
During normal operaon this breaker can remain in the “ON” posion, and the “HOUSE” switch can be used
to control the ow of current. The main ground for all DC accessories is ed into the common ground on all
baeries. For a detailed drawing of the baery management panel connecons, see the diagram in secon
10.4.1 of this chapter.
10.1.2 Addional Emergency Parallel
As an addional feature, the 280DC-X management panel contains a secondary “EMERG PARALLEL”
switch. It allows you to mechanically link the starboard “cranking” baery to the house baery. Furthermore,
engaging both “EMERG PARALLEL” switches will connect all three baeries into a single bank. The switches
should remain in the “OFF” posion when not in use. To prevent voltage spikes or drops which can damage
electrical components, you should trip the DC Mains 1 breaker prior to cranking engines with the house
baery in parallel. Once you are running, the breaker can be reset to allow the full alternator output to
power the electronics. This is a safety feature and should not be used in-lieu of the VSR’s to charge baeries
while underway. Doing so, could result in premature baery failure and increases the risk of electrical failure
while at sea.
10.1.3 Bilge Pumps / Float Switches
Your 280DC-X is equipped with two 1500 GPH bilge pumps located a and two 500 GPH bilge pumps
located forward. Each pump is connected to a oat switch which automacally triggers the pump when
water comes to rest in the bilge. The oat switches are connected to the baery management panel through
the hull harness and receive power from the breakers on the right side of the panel. These breakers are
constantly energized and ensure the safety of your boat even when the baery switches are in the “o”
posion. The pumps can be manually engaged using the switch at the dash.
The forward bilge pumps are accessible under the port side sink and under inspector plate in the starboard
helm storage area.
Inspect the operaon and condion of your bilge pumps regularly. Acvate the pump by liing the oat
switch. Once the oat switch is released the pump should shut o. It is important to keep the bilge area clean
and free of debris, which may prevent proper operaon of the oat switch, and cause damage to the pump.
