Install the Ground
IMPORTANT:
An earth ground rod is strongly recommended and should be no
further than 12 feet (3.7 m) from the CAPXM 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 CAPXM for correct grounding materials and installation
procedures. A proper ground is critical to minimizing risk for the CAPXM from
damaging electrical transients.
1.
Connect the ground wire (12 AWG or larger) to the CAPXM main earth
ground connection.
2.
Run the wire from the CAPXM to suitable earth ground.
NOTE:
Shield connections on boards should not be connected to main earth
ground connection.
