ET107 Weather Station
2. Hardware Installation
Do not install near power lines. If any part of the tower
comes in contact with power lines you could be KILLED.
Contact local utilities for the location of buried utility
lines before digging or driving grounding rods.
Do not fit the 3 meter ET Tower sections together until the
appropriate time. Once attached, they cannot be detached.
The ET Tower provides a support structure for mounting the ET107 weather
station components. FIGURE 2-1 shows a typical ET Tower installation
option. The tower is designed to withstand winds of 100 mph. The lightning
rod assembly is attached after the instrumentation enclosure is installed.
FIGURE 2-1. ET tower installation with currently-available AC power
option
User supplies valve box at base of station and weatherproof
enclosure for transformer. See FIGURE 2-1.
The AC power supply option at one time included a step-down
transformer instead of the power supply. Appendix E, Step-down
Transformer Installation, provides information about using the
step-down transformer.
