Step 6: Connecting the DC Cables
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. Table 1-2
on page 1–10 specifies the minimum DC cable size and maximum fuse
size for the Freedom HW.
Do not route your DC cables through an electrical distribution panel,
battery isolator, or other device that will cause additional voltage drops.
Figure 1-8 shows the DC end for your reference.
CAUTION
Before making the final DC connection, check cable polarity at both the battery
and the Freedom HW. Positive must be connected to positive; negative must be
connected to negative.
Reversing the positive and negative battery cables will damage the Freedom HW
and void your warranty. This type of damage is easily detected.
WARNING: Fire hazard
Use only copper wire rated 75 °C minimum. Make sure all DC connections are
tight to a torque of 108–120 in-lbf (12.2–13.6 N-m). Loose connections will
overheat.
