Step 7: Connecting To Port(S) On The Freedom Xc - Xantrex Freedom XC 1800 Owner's Manual

DC Grounding
To connect the DC ground:
1. The DC equipment grounding lug (DC ground lug) on the DC
end of the Freedom XC is used to connect the chassis of the
Freedom XC to your system's DC negative connection or
grounding bus point as required by electrical regulations.
2. 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.
3. 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
guide. If you are using different sizes, refer to the applicable
installation code for DC grounding details.
4. See Figure 7 for the location of the DC ground lug. Make
sure to tighten the bolt on the DC ground lug to a torque of
23 in-lb (2.6 N-m) of force. Apply an anti-corrosion
compound to the copper wire prior to connecting to the DC
ground lug.
Vehicle
Use 8AWG minimum-sized, stranded 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).
See regulatory references below.
For DC voltage systems under 60 VDC in a vehicle installation, an 8AWG

Step 7: Connecting to Port(s) on the
Freedom XC
Connecting to ACC Signal
The Freedom XC can be wired to inhibit inverter operation in the
absence of a vehicle's ignition control signal. This feature can
avoid unnecessary battery drain that would otherwise occur if the
inverter was operated without a charging source such as the
vehicle alternator.
To enable ignition control:
1. Ensure that AC and DC power are both OFF.
2. Ensure the vehicle's ignition is turned to OFF position. It is
highly recommended to remove battery power by
disconnecting the vehicle's battery cables. Refer to the
vehicle's user manual for proper instructions on how to
disconnect the battery cables.
3. Locate the vehicle's ignition control wire from the vehicle's
ignition circuit. This wire must be fused appropriately at no
more than 5 A. Refer to the vehicle's user manual for
guidance.
4. Locate the ACC input (ignition signal input) terminal on the
right side of the connector. The left terminal is not used at
this time. See Figure 12
