T107 Weather Station 1.5 Determining True North for Wind Vane Orientation Magnetic declination, or other methods to find True North, should be determined prior to installing the weather station. True North is usually found by reading a magnetic compass and applying the correction for magnetic declination*; where magnetic declination is the number of degrees between True North and Magnetic North.
T107 Weather Station FIGURE 1-7. Declination Angles East of True North Are Subtracted From 0 to Get True North FIGURE 1-8. Declination Angles West of True North Are Added to 0 to Get True North 1.5.1 Web Calculator Since magnetic declination fluctuates with time, it should be determined each time the wind sensor orientation is adjusted. It can be accessed at: www.ngdc.noaa.gov/geomag-web Below is an example for Logan, UT.
T107 Weather Station A positive declination is east, while a negative declination is west. The declination in this example is 12º 24′ or 12.4º. As shown in FIGURE 1-6, the declination for Logan, UT is east, so True North for this site is 360 – 12.4, or 347.6 degrees. References EPA, (1987).

Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure 5. CAUTION The bottom enclosure bracket should slide between the top lip of the bottom strut mount bracket and the notch directly below. Move the bottom bracket if necessary, then bolt the bottom bracket down (see FIGURE B-7). Do NOT over tighten the bottom bracket. FIGURE B-7.
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure 6. NOTE The bottom enclosure bracket has a small metal locking mechanism. Push up on the small Phillips screw underneath the mechanism and slide it to the left. Once in place, put a small wire tie in the hole to the right of the locking mechanism (see FIGURE B-8). To remove the enclosure from the bracketing, cut off the wire tie, slide the lock to the right, and lift the entire enclosure off the bracketing. FIGURE B-8.
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure 7. Install the solar panel above the 10 x 12 enclosure, and face the solar panel south. See FIGURE B-9 for fully mounted solar. FIGURE B-9. Mounted Solar Panel IMPORTANT 8. Throw a blanket or box over the solar panel to prevent any voltage output. 9. Route the solar panel cable and power cable coming from the main T107 enclosure into the conduit at the bottom of the 10 x 12 enclosure.
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure 10. Wire the solar panel to the CH100 terminal blocks as follows. Solar Panel to CH100 Red: CHG Black: CHG NOTE Polarity makes no difference. Connect one wire per CHG terminal block. 11. Remove the blanket or box from the solar panel once it’s wired in place. 12. Wire the power cable coming from the T107 station as follows.
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure 13. Follow the Installation of Battery procedure provided in FIGURE B-10. Plug the battery into the connector on the CH100 marked “INT”. FIGURE B-10. Procedure for installing and connecting battery 14. An extra loop of ground wire was sent with the station. Use it to ground the enclosure to the grounding rod system. The external ground lug is mounted on the bottom left hand corner of the 10 x 12 enclosure. 15.
Appendix B. PS24 24 Ahr Power Supply and 10 x 12 inch Enclosure CAUTION The enclosure needs to be sealed up tight so don’t be stingy with the putty. 17. Put both bags of desiccant inside of the enclosure. 18. Stick the humidity indicator card on a wall inside of the enclosure. CAUTION Pink on the humidity indicator card means it’s time to change the desiccant. Change the desiccant at least every year. However, it’s often wise to change the desiccant every six months. 19. Close the enclosure lid.
