Install the Ground
IMPORTANT:
An earth ground rod is strongly recommended and should be no
further than 12 feet (3.7 m) from the controller and use a minimum of 12 gauge
wire in most cases. The type and length of earth ground rods vary by region.
Contact the AHJ (Authority Having Jurisdiction) in the municipality where you
plan to install the controller for correct grounding materials and installation
procedures.
1. Connect the ground wire (12 AWG or larger) to the controller ground lug.
2. Run the wire from the controller to suitable earth ground.
NOTE:
Shield connections on boards should not be connected to ground lug.
