This guide for use by qualified installers only

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.
