Installation
26
If your battery bank is connected in parallel, you should
cross-connect the load by connecting the positive (+) cable
from the unit to positive terminal of the first battery.
10. Connect the negative (-) cable from the Freedom Inverter/
Charger directly to the negative post of the house or
auxiliary battery bank or the ground side of a current
shunt. Tighten securely.
If your battery bank is connected in parallel, you should
cross-connect the load by connecting the negative (-) cable
from the unit to negative terminal of the last battery.
Cross-connecting helps to balance the battery bank.
Note: If you are installing the unit in a vehicle, do not use
the vehicle frame, frame ground, or a ground bonding
system as the negative conductor.
You may see a spark when the final battery connection is
made. This is normal.
Warning
Do not make this final connection in the presence of flammable
fumes.
11. Check over your cable installation. Make sure that all
connections are clean and tight.
Warning
The Freedom Inverter/Charger is not DC reverse polarity protected.
Be very careful to connect the negative and positive cables correctly.
If the cables are revered, you will damage your unit and void your
warranty.
Step 5: Install battery cable fuses
To meet electrical codes, a UL Listed DC Rated slow blow class
“T” fuse must be installed in the positive (+) battery cable
within 18 inches of the battery. This fuse protects the battery
and cables when you have a short circuit. The inverter is
protected internally; it will not blow a properly sized fuse.
The recommended fuse and fuse holder is available from your
dealer or from Heart Interface.
