Installation Continued
7.
Run your cables free from sharp objects and hold each of them in place with cable ties.
Coil excess cable,
do not cut or shorten the length of the cables
as there are in-line
fuses located 4 inches from the end of each positive (red) cable. These fuses are in place to
protect the charger and output cables in the event of a short or reverse polarity.
8.
Connect the DC output cables as illustrated on page 8. Make sure the black wire is connected
as illustrated to the negative side of the battery and the red wires are connected to the positive
side of the battery.
9.
Make sure all DC connections are tight and correct.
10.
Locate the AC power cord in an open-air area of your boat at least 21 inches from the
charger, batteries and fuel fill lines.
11.
Connect a heavy duty U.L. approved extension cord to the battery charger first. After
connecting the extension cord to the charger then proceed to plug the extension cord to
a nearby 120VAC GFCI protected (Ground Fault Circuit Interrupt) outlet. Always remove the
extension cord from the 120VAC outlet first when charging is completed, followed by
unplugging the charger.
You are now connected and charging your batteries. View the LED indicators. Assuming your
batteries are discharged you should observe both the blue "Power" LED and the red "Charging"
LED on, indicating charging mode is in process.

When connecting each jacketed battery charger cable, make sure it is connected
to only
one 12 VDC battery
and observe the polarity and color of all connections:
Red Wire = + (Positive) Battery connection
Black Wire = - (Negative) Battery connection
The black wire can never be connected to a terminal with red wires. Only black.
Important: The pair of red and black wires in 1 cable jacket MUST GO TO THE SAME 12VDC battery.
Each charger cable
must
be connected to 1 battery,
just as shown. Observe
black to (-) and red to (+).
Do this for each battery.

IMPORTANT NOTICE
If only two batteries are used with a 3 bank charger, then connect the unused output
cable to either one of the two batteries, as instructed in item 8 above
Always connect each charger output to a single 12V battery even if the batteries
are wired series for 24V or 24V with an engine battery.
