    To eliminate the possibility of a short circuit while installing the panel,  

  disconnect the main positive cable from all batteries.

    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.

    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 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. 

    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.

  

  If at any time you are not satisfi ed with this product, you may return it 
  for a refund or replacement.

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.
