Install the Ground

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