Blue Sea Systems PN 8408 Manuel D’Utilisation

 

  Disconnect all AC power originating on or off the vessel. This includes  
  inverters, generators, shore power attachments and any other device  
  capable of supplying AC power to the ship’s circuits.

  Disconnect the main positive DC cable from all batteries to eliminate the  
  possibility of a short circuit and to disable the inverter while installing the  
  distribution panel.

  All panel components are sized for 12 or 24 Volt systems. Use the labels  
  provided to permanently identify the system voltage and its type (DC) as  
  required by ABYC. Apply the appropriate voltage label to the recessed  
  area on the front of the panel.  

  If this panel is to serve as your main shore power disconnect circuit   
  breaker, select a location which is not more than 10 feet from the shore  
  power inlet or the electrical attachment point of a permanently installed  
  shore power cord as measured along the conductors of the feed wires. If  
  it is more than 10 feet, additional fuses or circuit breakers must be    
  installed within 10 feet of the shore power inlet.

  Select a mounting location which is protected from water on the panel  
 front and back and is not in an area where flammable vapors from  
  propane, gasoline or lead acid batteries accumulate. The circuit breakers  
  used in marine electrical panels are not ignition protected and may ignite  
  such vapors.

  Using the panel template provided, make a cutout in the mounting    
  surface where the distribution panel is to be mounted. Do not yet fasten  
  the panel to the mounting surface.

 These instructions are intended to provide assistance with the  

 

  installation of this product, and are not a substitute for a more  

 

  comprehensive understanding of electrical systems. We strongly    
  recommend that a competent electrical professional perform the  

 

  installation of this product.

]

 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 as 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.

]

 The shunt must be installed in the negative line to avoid damage to the  

  meter. Positive voltage applied to digital meter terminals #4 and #5 will  
  cause damage to the meter not covered by warranty.

]

 The vessel’s shore power cord must be disconnected form shoreside  

  power before installing this electrical panel.

]

 If an inverter is installed on the vessel its power leads must be  

 

  disconnected at the battery before the panel installation. Be aware that  
  many inverters have a “sleep mode” in which their voltage potential may  
  not be detectable with measuring equipment.

]

 If an AC Generator is installed aboard it must be stopped and rendered  

  inoperable before the panel is installed.

]

 Verify that no other AC source is connected to the vessel’s wiring before  

  the panel is installed.

  Determine the positive feed (red) and negative return (black or yellow)  
  wire size by calculating the total amperage of the circuits that will be  
  routed through the panel. Blue Sea Systems’ electrical panels are rated  
  at 100 amp total capacity. The positive feed wire must be sized for 3%  
  voltage drop at the 100 amp panel rating or the maximum amperage  
  that will be routed through the panel in any particular installation, 
  whichever is less. It is recommended that the positive feed wire be sized  
  for the full panel capacity, which, in most cases, will require at least 2  
  AWG wire, assuming a 10 foot wire run between the panel and the    
  batteries in 12 volt systems. Refer to the Wire Sizing Chart for other  
  situations. In the case of panels with two or more columns of breakers,  
  jumpers from positive bus to positive bus and from negative bus to    
  negative bus should be the same size as the positive feed and the    
  negative return wires. 

  Remember that the length of the circuit is the total of the positive wire  
 from the power source and the negative wire back to the DC Negative
  Bus. Be certain that there is a fuse or circuit breaker of the correct size  
  protecting the positive feed wire.

  The DC digital meter shunt must be installed in the negative line of the  
  circuit whose current is to be measured. Refer to the DC meter  

 

  installation and operation manual prior to installing the shunt. Review the  
  Theory of Operation, Use, Installation Overview, Installing Shunt, Wiring  
  Diagram and Wire by Wire Instruction sections. Observe all warnings  
  regarding the shunt installation.  

  Connect a negative return wire from the negative bus on the panel to DC  
  negative and ultimately the load side of the shunt. Connect a positive  
  feed wire from the positive bus on the panel to DC positive. Be certain  
  that there is a fuse or circuit breaker of the correct size protecting the  
  positive feed wire.
