Once you have installed the unit, run a ground wire between the ground stud on the
bottom of the battery box enclosure and a known good earth ground. You route the
ground wire through one of the conduit fittings.
Use stranded copper wire to earth ground and keep the length as short as possible.
Clamp or braze the ground wire to the ground bed conductor (typically a stranded
copper AWG 0000 cable installed vertically or horizontally).
Using a high-wattage soldering iron, tin the wire ends with solder before you insert
them into the chassis ground lug.
Run the ground wire so that any routing bend in the cable has a minimum radius of
30.48 cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
For more information on grounding or if your installation uses cathodic protection, refer to
