Step 6: Connecting the DC Cables
NOTICE
REVERSE POLARITY
l
Check cable polarity at both the battery and the Freedom XC
PRO before making the final DC connection. Positive must be
connected to positive; negative must be connected to
negative. Check to see if the reverse polarity LED (see
) is not illuminated.
l
Reversing the positive and negative battery cables will blow
a fuse in the Freedom XC PRO and void your warranty.
Failure to follow these instructions can result in equipment
damage.
WARNING
FIRE HAZARD
Use only copper wire rated 75 °C minimum. Make sure all DC
connections are tight to a torque of 71–80 in-lb (8–9Nm) of force.
Loose connections will overheat.
Failure to follow these instructions can result in death, serious
injury, or equipment damage
.
Follow the procedure given below to connect the battery leads to
the terminals on the DC end. The cables should be as short as
possible and large enough to handle the required current, in
accordance with the electrical codes or regulations applicable to
your installation.
specifies the minimum DC cable size
and maximum fuse size for the Freedom XC PRO.
If at all possible, minimize routing your DC cables through an
electrical distribution panel, battery isolator, or other device that
will cause additional voltage drops which can degrade the
inverter/charger’s ability to operate the loads.
shows the DC end for your reference. The reverse
polarity LED will light up when the DC cables were reversed
during installation. Reversing the connections may void the
