WARNING
The Dual Circuit Plus
™
Battery Switch turns the house and start batteries
on at the same time, but isolates them from each other. Battery isolation
protects the start battery from being discharged from the many house loads
like refrigerators, stereos, and lights, preserving it for starting the engine.
Battery isolation also protects sensitive electronics from voltage spikes and
sags that may occur during engine starting. The Dual Circuit Plus
™
Battery
Switch simplifies battery switch operation--it performs the same operation
as three ON/OFF battery switches. The engine and house batteries are
turned ON at the same time when the boat is boarded and OFF when the
boat is not in use. This minimizes the opportunity for error. In an emergency
requiring that both batteries be combined—e.g., a discharged start battery—
the operator simply turns the switch knob to the COMBINE BATTERIES
position.
The Dual Circuit Plus
™
Battery Switch automates the charging of two battery
banks when coupled with an Automatic Charge Relay (PN 7610 or PN
9112). This combination creates a complete battery management system
of isolated battery circuits, emergency cross connect (emergency parallel)
functions, and automated charge management.

How it works
Installation
1. Disconnect all DC power
To eliminate the possibility of a short circuit while installing the panel,
disconnect the main positive cable from all batteries.
2. Select mounting location and cut opening
Select a mounting location that is protected from water on the panel front
and back and is not in an area where flammable vapors from propane,
gas or lead acid batteries accumulate.
Using the panel template provided, make a cut out in the mounting
surface where the panel is to be mounted. Do not fasten the panel to the
mounting surface.
3. Install LED negative feed wire
Use a 16 AWG wire to connect the LED negative feed (Yellow) wires to a
DC negative bus.
4. Electrical Connections
Battery cable terminals must be attached under battery switch stud nut
and lock washer. The electrical connection illustration is general in
nature and is not meant to be a guide for the wiring of any specific
vessel. There are many possible wiring configurations. Consult your
marine electrical professional for the wiring system applicable to
your boat.
Make appropriate adjustments to the wiring diagram to suit your specific
installation and equipment. Fusing may be appropriate in several of the
lines depending on the proximity of components, conductor sheathing,
and the conductivity of the surrounding structure. Consult the
Wire
Sizing Chart
to determine the appropriate wire sizes.
5. Apply Labels and Mount Panel
Apply a label to each of the circuits from the label sheet provided.
Additional labels are available from Blue Sea Systems. Fasten the
panel to the mounting surface using the screws provided.

If the installer is not knowledgeable about electrical systems,
consult an electrical professional.
]
If either the panel front or back is to be exposed to water it must be
protected with a waterproof shield.
]
Standard Blue Sea Systems battery management panels are ignition
protected as shipped.
]
Custom panels are ignition protected when supplied with ignition
protected circuit breakers.
]
The main positive connection must be disconnected at the battery post
to avoid the possibility of a short circuit during the installation of
this distribution panel.
