WARNING
Dual Battery Main Distribution Panel
One Selector Battery Switch
PN 8687/8691
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 fl ammable 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 specifi c
vessel. There is a wide range of wiring confi gurations possible.
Consult your marine electrical professional for the wiring system
applicable to your boat.
Make appropriate adjustments to the wiring diagram to suit your
specifi c 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. Use
the panel mounting screws supplied with the panel to secure the panel
to the mounting surface. Additional labels are available from
Blue Sea Systems.

@ 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.
@ The panels must not be installed in explosive environments such as
gasoline engine rooms or battery compartments because the circuit
breakers are not ignition protected.
@ 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.

Caution: ABYC Interrupt
In certain circumstances, main DC circuit breakers may have to break
very high amperages. The ability of a circuit breaker to safely break high
amperage is its Ampere Interrupt Capacity (AIC) rating. AIC is a function
of a battery’s Cold Cranking Amperes (AIC) capacity. According to ABYC
E-11 standards, circuit breakers shall have a DC voltage rating of not less
than the nominal system voltage, be capable of an interrupting capacity
according to the values in the table below, and remain operable after the
fault. For example, a boat with a group 24 or 27 battery may have as much
as 650 CCA. The DC main circuit breaker for this circuit must have an AIC
rating of 1500 Amperes.
Blue Sea Systems Battery Management Panels contain thermal (push
button reset) circuit breakers rated at 15A. These circuit breakers are
suitable for 24-hour circuits connected directly to 12V or 24V battery banks
with CCA capacities less than 660A.
Installation of this panel in systems with battery banks of 660A or higher
should include an additional fuse or circuit breaker of appropriate interrupt
capacity in the line between the battery bank and the pushbutton circuit
breakers to comply with ABYC E-11 and NFPA 302.
