Connecting the Equipment Ground
The Freedom HF has a ground stud on the side of the unit as shown in
Figure 1-4 . Follow the guidelines in “Grounding Locations” to connect
the inverter’s chassis to the ground.
Grounding Locations
You must connect the equipment ground stud to a grounding point—
usually the vehicle’s chassis or DC negative bus ground—using
recommended copper wire (if insulated then green insulation with or
without one or more yellow stripes) or larger.
For recommended equipment ground cable size, see below.
In general, the equipment ground cable size must not be smaller than one
AWG size than the supply cable.
WARNING: Fire hazard
Never operate the Freedom HF without properly connecting the equipment
ground. A fire hazard could result from improper grounding.
