Wire Routing guidelines
Suggested cable size for DC input connections is 00 AWG. See Table 1-1 for the fuse rating required at
the battery end of the positive DC input cable.
Build the cables before rough fitting them to the vehicle. Note any points that will require special attention
to avoid chafing or exposure to heat sources. Eliminate potential trouble areas by installing clamps,
protecting wiring harnesses with plastic wrap, and installing grommets in feed through holes.
To prevent chafing, cables, plumbing, and installed equipment should not come into hard contact with
each other. Because the bodywork and structure can flex during operation, at least a quarter inch
clearance is advised between cables and nearby equipment. Do not route cables in high heat areas
without adequate thermal protection. Avoid exposure to chemical damage by using protective conduit or
wrap.
Torque DC input cable fasteners to 12.2 -13.6 Nm.
Torque Chassis Ground cable fastener to 6.6 – 7.3 Nm.

General AC wiring considerations
AC Wiring Connectors –
AC wires are fixed to their respective barrier strip terminals by
clamp screws. The amount of insulation to be stripped off the individual wires should not be so
much that it is visible outside the connector.
AC and DC Wiring Separation –
Do not mix DC and AC wiring configurations. Do not
use the same conduit or panel. If wires must cross, only do so at 90° to one another. If
