Procedure 5: TP1-GR Ground Kit Installation
a. Proper earth grounding of the system may be required for both personal safety and reliable
system function, we recommend a qualified electrician install the grounding kit.
b. If the station is directly connected to the Host computer but not properly grounded and isolated,
the Host computer can be damaged by environmentally induced electrical surges.
c. This kit is for ground installations only. Do not use the TP1-GR kit for rooftop installations.
A qualified electrician should specify and install the earth ground system for a roof mounted
weather station, if required.
1. Connect the lug of the 14 AWG copper wire to the connector labeled Ground Lug on the bottom
of the WeatherHawk station (Figure 17).
2. Mount the tripod coupling on the tripod mast so
that it clamps the 14 AWG wire against the tripod
(1 of Figure 18).
3. Drive the ground rod into the soil using a fence
post driver or sledge hammer leaving about
3 inches (7.5 cm) above the ground.
4. Loosen the middle screw in the tripod coupling.
5. Place one end of the #4 cable in the tripod coupling
hole then tighten the screw
(2 of Figure 18).
6. Attach the other end of the #4 cable to the ground
rod using the ground rod coupling (Figure 19).
