DC Grounding Locations
You must connect the DC 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.

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.
