terminal, but do not overtighten.
DC Grounding
To connect the DC ground:
The equipment grounding lug on the DC end of the Freedom HW is used
to connect the chassis of the Freedom HW to your system’s DC negative
connection or grounding bus point as required by electrical regulations.
Use copper wire that is either bare or provided with green insulation. Do
not use the DC Ground Lug for your AC grounding. (See the AC wiring
instructions in this section.)
Follow the guidelines below that correspond to the specific type of
installation. These guidelines assume you are using the DC supply cable
and fuse sizes recommended in this manual. If you are using different
sizes, refer to the applicable installation code for DC grounding details.
Recreational
Vehicle
Use 8AWG copper wire and connect it between the Chassis Ground lug
and the vehicle’s DC grounding point (usually the vehicle chassis or a
dedicated DC ground bus).
