Blue Sea Systems 8499 AC 2 Sources + 4 Positions - Manual (Page 2)

Fasten the panel to the mounting surface using the panel mounting
screws supplied with the panel.
7. Testing
]
Connect the shore power cable to the boat AC power inlet. Do not
connect the shore power cable to the shore power pedestal. Instead
run the shore power cable such that the shore power plug is next to
the AC panel. With an Ohmmeter verify that the pins of the shore
power plug are connected to the appropriate terminals of the panel.
Refer to ABYC E-11 Figure 13 or 14 or NEC / NEMA documents for
the standard pin arrangements for your plug.
]
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 8459/ 8466/ 8467/ 8468/ 8469/ 8499-120 Volt AC
PN 3459/ 3466/ 3467/ 3468/ 3469/ 3499-120 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 8559/ 8566/ 8567/ 8568/ 8569/ 8599-230 Volt AC
PN 3559/ 3566/ 3567/ 3568/ 3569/ 3599-230 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.
]
Turn off the shore power and test with the alternate source.
Note
This Blue Sea Systems electrical distribution panels is furnished with 15
amp or 8 amp circuit breakers for branch circuits to satisfy the vast
majority of marine circuit protection situations. 15 amp circuit breakers
are used in all 120 volt panels and 8 amp circuit breakers are used in all
230 volt panels.
The Purpose of a Panel
There are six purposes of a marine electrical panel:
l Power distribution
l Circuit (wire) protection
l Circuit ON/OFF switching
l Reverse Polarity Indication
l Metering of voltage and amperage (In panels with meters)
l Condition Indication (circuit energized)
Applicable Standards
l American Boat and Yacht Council (ABYC) Standards and
recommended Practices for Small Crafts sections: E-8, Alternating
Current Electrical Systems on Boats.
l United States Coast Guard Code of Federal Regulations 33, Part
183, Subpart I, Electrical Systems on Boats.
Related Products from Blue Sea Systems
l High Amperage Fuses and Circuit Breakers for positive feed wires
l High Amperage Battery Switches
l Terminal Blocks and Common Bus Connectors
l AC Distribution Panels
l DC Distribution Panels
Optional Branch LED’s
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.
The Purpose of the AC Main Source Selector Panel
Two live sources of AC power, such as shore power and inverter power,
or shore power and a generator, cannot be electrically connected. The AC
Main Source Selector panel is designed to prevent both sources from
being connected to the circuit simultaneously.
4. Install feed circuit wires, source 1 and source 2
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 fuse or circuit breaker must be installed within 10 feet of the
shore power inlet. The measurement is made along the conductors.
5. Installation of Backlight System
Remove the blank labels installed in the panel before installing your
branch circuit labels. Apply a label for each of the branch circuits from
The 30 basic labels provided. If the appropriate label is not included,
Individual labels are available from Blue Sea Systems for specific
Applications. Refer to the label order form for a complete listing of
individual labels.
Install the feed wires from AC source 1 and AC source 2. Refer 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.
6. Apply circuit labels and mount panel
Apply a label for each circuit form the 10 basic labels provided.
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.
