Grounding Locations
You must connect the equipment ground lug 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.
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.
For recommended equipment ground cable size, see below.

a
No. 8 AWG
Marine
b
No. 2/0 AWG
NOTE
: There are no restrictions on length for the equipment
ground cable but try to make it as short as practical to a secure
chassis connection. In general, the equipment ground cable size
must not be smaller than one AWG size than the supply cable.

Based on ABYC E-11 § 11.16 and A-31 § 31.6.5.
Step 4: Connecting the AC Input Wires
WARNING
ELECTRIC SHOCK AND FIRE HAZARDS
Make sure wiring is disconnected from all electrical sources before
handling. All wiring must be done in accordance with local and
national electrical wiring codes. Do not connect the output
terminals of the Freedom XC PRO to any incoming AC source.
Failure to follow these instructions can result in death, serious
injury, or equipment damage
.
General AC Wiring Considerations
AC Wiring Connectors
Where applicable, connect AC wires with crimp-on splice
connectors. The amount of insulation you strip off individual wires
will be specified by the connector manufacturer and is different for
different types of connectors.
AC and DC Wiring Separation
Do not mix AC and DC wiring in the same conduit or panel. Where
DC and AC wires must cross, make sure they do so at 90
°
to one
another. Consult applicable codes for details about DC and AC
wiring in close proximity to each other.
