Basic Installation Procedures
This

13. Route the negative cable through the right side strain relief
clamp and connect the cable from the negative post of the
battery to the negative DC terminal of the inverter.
14. Fasten the DC terminal nut (set aside earlier) to the terminal
bolt. Tighten the nut to a torque of 71–80 in-lbf (8–9 N-m). Do
not overtighten. Make the connection snug enough so the cable
lug does not move around on the DC terminal. Center it through
the DC knockout hole and do not let it touch the edge.
15. Replace the DC compartment cover.
DC Grounding
To connect the DC ground:
The equipment grounding lug on the DC end of the Freedom X is
used to connect the chassis of the Freedom X 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 X 1000, use a wire of gauge 3AWG minimum. For the
Freedom X 2000, use a wire of gauge 1/0AWG minimum.
WARNING
FIRE HAZARD
Do not complete the next step if flammable fumes are present. Explosion
or fire may result if the disconnect/battery selector switch is not in the off
position. Thoroughly ventilate the battery compartment before making
this connection.
Failure to follow these instructions can result in death or serious injury.
