Panel Mounting and Testing

1.Apply branch circuit labels and mount panel

Apply a label for each circuit from the label set provided. If the appropriate label is not included, extended label sets are available through retail suppliers, and over 500 individual labels are available directly from Blue Sea Systems. Please go to www.bluesea.com to order stock or custom labels for specific applications.

Fasten the panel to the mounting surface using the screws provided.

2.Testing

]Reconnect the main positive cable to the battery terminals and turn the main switch on to supply power to the panel. Turn on all branch circuits and test the voltage at the panel. Compare this voltage to the battery terminal voltage to determine that the voltage drop is within 3%. With all branch circuits still on, test the voltage at one device on each circuit to determine that there is a 3% or 10% drop as is appropriate.

]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 8408 / PN 3408—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 8508 / PN 3508—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 AC and DC meter installation and operation manual. Reference the Theory of Operation, Use, Installation Overview and operations sections. Verify meter functions.
