Connecting the Panel to Earth Ground
For maximum protection from lightning strikes and transients, connect the lower-
right circuit board screw to earth ground as shown in Figure 5 below. Use 16-
gauge, solid copper wire from an earth grounded cold water pipe clamp to the
panel.
Note : For best results, it is recommended that you crimp a spade lug on the wire
end at the panel and secure the lug under the circuit board screw as shown in
Figure 5 below.
