Machine Grounding
It is strongly recommended that the machine be earth grounded. A dedicated copper rod 8 feet or so in length
should be driven into the ground near the TMC. A ground wire should then be run from the location shown in figure
9. The copper wire should exit the electrical cabinet in the lower right-hand corner as shown in figure 10. Make sure
the foam where the copper wire goes through seals the cabinet from external debris. The wire should be 6 gage in
size.
