Basic Installation Procedures
Anderson Connectors
The Freedom HF 1055 EMS and 1800 EMS models are pre-wired with an
Anderson
1
connector that attaches to matching terminal connectors in
certain trucks and vehicles.
DC Grounding
To connect the DC ground:
The equipment grounding lug on the DC end of the Freedom HF is used to
connect the chassis of the Freedom HF 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).
Marine Use copper wire that is bare or has insulation rated minimum
105 °C, and connect it between the Chassis Ground lug and the boat’s DC
grounding bus or engine negative bus. For the Freedom HF 1000, use a wire
of gauge 4AWG minimum. For the Freedom HF 1800, use a wire of gauge
1/0AWG minimum.
