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, as described in Section
2.2-1 of the weather station installation
manual. 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.

FIGURE 2-6. Guy Wire Installation
1.
Construct an assembly consisting of the top
plate, wire ropes, 3 thimbles, and 6 u-bolts.
a.
Place a thimble into each of the three
small holes of the top plate. Twist each
thimble slightly, as shown in Figure 2-7,
to accomplish this.
b.
Thread a piece of wire rope through
each of the three small top plate holes.
Double the wire rope back on itself
about 8 inches. Clamp the doubled
wire with two u-bolts per wire, forming a
loop. Fit the wire loop into the thimble
groove. Adjust the u-bolts as needed.
Once the thimble and wire loop are
fitted together, tighten the u-bolts to
secure the clamps.
