Blue Sea Systems 8511 AC 8 Position - Manual (Page 2)

Installation
(continued)
5. Install feed circuit wires
Install the feed wires from the AC main circuit breaker panel 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.
6. Installation of Backlight System
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.
7. Apply branch circuit labels and mount panel
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.
8. Testing
@ Using a multimeter where the power source is connected to the
panel verify:
PN 8097 / 3097 / 8411 / 3411-120 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 8197 / 3197 / 8511 / 3511-230 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.
Note
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.
