Part No. 90-0113-00
Fdmman2.p65 2/98
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.
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. However, if
necessary, it is possible to extend the cables.
Use proper extension terminals (Heart
Interface part #31-6000-01). Do not bolt the
terminals together and cover with tape.
Extension cables must be 00 AWG (2 AWG
for the Freedom 10), the same type of wire
supplied with the unit, and the total length for
each battery cable
must not exceed 10 feet.
Make sure the connections to the
extension cables are tight and properly
insulated. Do not attempt to open the case
and replace 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.
Tighten securely.
NOTE: If installing in a vehicle, do not
use the vehicle frame as the negative
conductor.
Freedom Inverter/Chargers are not
protected against DC reverse polarity. Be
very careful to connect the negative and
positive cables correctly or damage will
result and the warranty will be void.
WARNING
INSTALLATION
24
The positive battery cable (red heat
shrink insulation on the end) must be fused
and connected to the positive post of the
battery bank, or through a selector switch to
one or more battery banks.
A spark may be generated when the final
battery connection is made. This is normal; do
not be alarmed. However, do not make the
final connection in the presence of flammable
fumes.
Battery Cable Fusing
A fuse is required by the NEC to protect
the battery cables. The fuse must be installed
in the positive battery cable, within 18 inches
of the battery.
Refer to the Installation Guide for
installation suggestions.
