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.

Installation  
Caution  
1. Disconnect all DC power  
Caution: ABYC Interrupt  
To eliminate the possibility of a short circuit while installing the panel,  
disconnect the main positive cable from all batteries.  
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.  
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 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.

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 specic  
vessel. There is a wide range of wiring congurations possible.  
Consult your marine electrical professional for the wiring system  
applicable to your boat.

Make appropriate adjustments to the wiring diagram to suit your  
specic 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.  
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.  
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.  
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.
