Basic Installation Procedures
This guide for use by qualified installers only.
Step 6: Connecting the DC Cables
The following instructions only apply to the following models: Freedom
HF 1000, Freedom HF 1055, Freedom HF 1800, and Freedom HF 1800 T.
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 2 on page 9
specifies the minimum DC cable size and maximum fuse size for the
Freedom HF.
Do not route your DC cables through an electrical distribution panel,
battery isolator, or other device that will cause additional voltage drops.
Figure 4 shows the DC end for your reference.
REVERSE POLARITY DAMAGE
Before making the final DC connection, check cable polarity at both the
battery and the Freedom HF. Positive must be connected to positive;
negative must be connected to negative.
Reversing the positive and negative battery cables will damage the
Freedom HF and void your warranty. This type of damage is easily
detected.
Failure to follow these instructions can damage the unit and/or
damage other equipment.
FIRE HAZARD
Use only copper wire rated 75 °C minimum. Make sure all DC
connections are tight to a torque of 216–240 inch-pounds (24–27Nm).
Loose connections will overheat.
Failure to follow these instructions can result in death or serious
injury.
