3. Loosen the set screws in the two brass ground lugs attached to the center
bracket of the tripod (Figure 2-5). Strip 1 inch of insulation from the other
end of the 4 AWG wire and insert it into the lower ground lug. Tighten
the set screw. Strip 1 inch of insulation from one end of the 12 AWG wire
and insert it into the upper ground lug. Tighten the set screw. The other
end of the 12 AWG wire will attach to the ground lug of the
instrumentation enclosure.
4. Attach the lightning rod to the mast as shown in Figure 2-1. If the weather
station includes an 019ALU crossarm, attach it to the mast first. Loosen
the two screws on the lightning rod mounting bracket. Position the
mounting bracket 4 inches down from the top of the mast, then tighten
both screws evenly. Make sure the lightning rod set screw is tight.
