DC Wiring
Two battery cables are provided with the unit. Both are black. The positive (+)
cable has a piece of red heat shrink insulation on the end. Keep in mind that high
current will pass through the DC wiring. All wires must be properly sized and all
connections clean and tight.
It is recommended that the battery cables not be lengthened at all. However, it is
possible to extend the cables if necessary. Extension cables must be 35.0 mm

ES,
the same type of wire, and the total length for each battery cable must not exceed
3.04 m from the inverter to the battery terminal.
Make sure the connections to the extension cables are tight and properly insulated.
Do not attempt to open the case and replace the battery cables.
The negative (–) cable should be connected directly to the negative post of the
battery bank or the ground side of a current shunt. Do not use a negative bus or
bonding system as the negative conductor. Tighten securely.
The positive (+) battery cable will commonly lead to a positive distribution point.
This point typically connects to a battery switch rather than to the battery. The
total length should not exceed 3 m and should be fused.
A spark may be generated when the final battery connection is made. This is
normal and do not be alarmed. However, do not make the final connection in the
presence of flammable fumes.
CAUTION: Reverse polarity hazard
The Freedom 10 is not DC reverse-polarity protected. Be very careful to connect the
negative and positive cables correctly, otherwise damage will result and the warranty will
be void.
