Earthing Locations
You must connect the equipment earth lug to an earthing point—
usually the vehicle’s chassis or DC negative bus earth—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 earth lug to a torque of
2.6 N-m of force. Apply an anti-corrosion compound to the copper
wire prior to connecting to the DC earth lug.
For recommended equipment earth cable size, see below.

NOTE : There are no restrictions on length for the equipment
earth cable but try to make it as short as practical to a secure
chassis connection. In general, the equipment earth cable size
must not be smaller than one size than the supply cable.
