8. BATTERY BANK INSTRUCTIONS
BATTERY BANK ASSEMBLY
WARNING: Read these safety
instructions before assembling the
battery bank.
• Connect batteries ONLY in parallel
(negative terminals together to one
cable; positive terminals together
to the other cable), as shown in the
Battery Bank Example.
• Do not connect 12V batteries in a
series with the negative of one battery
connected to the positive of the next.
DANGER: CONNECTING INCORRECTLY
MAY RESULT IN VOLTAGE HIGH
ENOUGH TO CAUSE ELECTROCUTION.
• While assembling the battery bank, wear
splash-resistant ANSI-approved safety
goggles and electrically insulated gloves.
• Connect ONLY similar batteries together
in a battery bank. Do not connect old
to new, flooded to gel cells, or batteries
with different capacities.
• Use extension cables with the specified
gauge (or thicker).
6' or less: 6 AWG; 6-10': 4 AWG
WARNING: RISK OF EXPLOSIVE GASES.
• Assemble the battery bank in a clean,
well-ventilated location, away from
ignition sources and flammable materials.
• To reduce risk of battery explosion,
follow these instructions and those
published by the battery manufacturer and
manufacturer of any equipment you intend
to use in vicinity of a battery. Review
cautionary markings on these products.
CONNECTING THE BATTERIES
IN PARALLEL
1. First, connect all of the positive
terminals to each other.
2. Next, connect all of the negative
terminals to each other.
3. Connect the negative and positive
output cables to opposite ends of
the bank. Do not allow the output
cables to touch one another.
9. OPERATING INSTRUCTIONS
1. Connect the converter (see Connecting
Converter Cables section.
2. Switch the converter's ON/OFF switch
to the ON (I) position.
3. The GREEN LED indicator will light,
indicating the converter is receiving power.
4. Switch the converter's ON/OFF
switch to the OFF (O) position. (The
GREEN LED may flash briefly and/or
the internal speaker may make a brief
"beep". This is normal.)
4. Test the voltages at the output cables,
to make sure that the battery bank is
correctly wired.
5. If the voltage is higher than 13 volts,
part of the battery bank is probably
connected in series (a negative
terminal of one battery attached to a
positive terminal of another) instead of
in parallel.
6. Carefully examine the diagram and
correct the wiring before attaching to
the converter.
7. Make sure the converter's switch is
set to OFF (O).
8. Connect the output cables from the
battery bank to the converter.

purposes.
5. Make sure the device to be operated
is turned OFF.
6. Plug the device into the converter's
AC outlet.
7. Switch the converter's ON/OFF switch
to the ON (I) position.
8. Turn the device on.
9. To disconnect, reverse the above
procedure.
