Blue Sea Systems PN 8621 Merkblatt

 

Install the feed wires from the shore power inlet or other AC source,  

 

referring to the wire sizing chart to select the correct wire size. Connect  

 

the black AC hot, white AC neutral and green AC safety ground as  

 

shown in the illustration.

 

If the feed wires are from the shore power inlet or the electrical    

 

attachment point of a permanently installed shore power cord and the  

 

inlet or attachment point is more then 10 feet from this panel, an    

 

additional fuses or circuit breakers must be installed within 10 feet of  

 

the shore power inlet. The measurement is made along the  

 

 conductors.

 

The backlight board is a DC device.  When installing it in an AC panel  

 

both wire leads must be connected to an appropriate DC source and  

 ground.

 

Connect the yellow negative wire to a DC ground.  Connect the red  

 

positive wire to any DC positive supply, usually a switch that controls  

 

the vessel’s other nighttime illumination.

Apply a label for each of the branch circuits from the 30 basic labels 
provided. If the appropriate label is not included, the Extended Label 
Set of 120 labels may be ordered from your marine supplier (PN 8067). 
Individual labels are also available from Blue Sea Systems for specifi c 
applications. Refer to the label order form for a complete listing of 
individual labels.

Fasten the panel to the mounting surface using the panel mounting 
screws supplied with the panel.

 @

  Connect the vessel’s shore power and verify the Reverse Polarity  

 

 

light is not illuminated. If the red Reverse Polarity light is on then  

 

 

either the hot and ground or the hot and neutral wires have been  

 

 

crossed. Starting at the panel, trace the connections  back as far  

 

 

as necessary to locate the error.

 @

  Using a multimeter where the power source is connected to the  

  panel 

verify:

 

 

PN 8618 / PN 8620 - 120 Volt AC

 

 

 

a. 

120 volts between hot and neutral

 

 

 

 

(nominal, this may vary depending on source voltage) 

 

 

 

b. 

120 volts between hot and ground.

 

 

 

c. 

0 volts between neutral and ground.

 

 

PN 8619 / PN 8621 - 230 Volt AC

 

 

 

a.     230 volts between hot and neutral

 

 

 

 

(nominal, this may vary depending on source voltage) 

 

 

 

b. 

230 volts between hot and ground.

 

 

 

c. 

0 volts between neutral and ground.

 @

  Turn on each branch circuit to verify power to each circuit.

 @

  Review the meter installation and operation manual. Reference  

 

 

the Theory of Operation, Use, Installation Overview and  

 

 

 

operations sections. Verify meter functions.

 

This Panel is supplied with LED’s pre-installed in all optional branch  

 

positions. For future expansion of the panel remove the hot leg of the  

 

LED from the AC Neutral Bus and connect it to the Load side of the  

 

branch circuit breaker.

All Blue Sea Systems’ AC electrical distribution panels are furnished 
with 15 amp or 8 amp circuit breakers for branch circuits. 15 amp 
circuit breakers are used in all 120 volt panels and 8 amp circuit 
breakers are used in all 230 volt panels. These ratings were selected 
to minimize the need for removing the panel’s circuit breakers and 
reinstalling different size circuit breakers. It is very rare to have more 
than this amount of current fl owing in any one circuit. Therefore, these 
circuit breakers will satisfy the vast majority of marine circuit protection 
situations.

There are six purposes of a marine electrical panel:
• Power distribution
•  Circuit (wire) protection
•  Circuit ON/OFF switching
•  Reverse Polarity Indication
•  Metering of voltage and amperage  (In panels with meters)
•  Condition Indication  (circuit energized)
