7.2 Sensor Mounting Brackets
Sensor mounting brackets provide a means of mounting the sensors to the
tower. General orientation of the mounting brackets is shown in FIGURE
7-14.
7.2.1 CM202, COM202SS, CM203, CM204, CM204SS, or CM206
1. Attach the crossarm at the desired height via the provided U-bolts and nuts
(FIGURE 7-15).
7.2.2 Gill Radiation Shields
7.2.2.1 41303-5A, 41003-5, 41005-5
1. Attach the radiation shield to the tower leg, tower mast, or CM200-series
crossarm with the U-bolt and nuts provided. If attaching to the tower leg
or mast, place U-bolt in the radiation shield’s side holes. If attaching to a
crossarm, place the U-bolt in the radiation shield’s bottom holes.
7.2.3 Solar Radiation Mounts
7.2.3.1 CM225 Solar Radiation Stand
1. If using a LI200X, LI190SP, or CS300, attach the LI2003S or 18356
leveling base to the CM225 using the three screws provided.
2. Attach the CM225 to a tower leg, mast, or CM200-series crossarm. If
attaching to a tower leg or mast, place the U-bolt in the CM225’s side
holes. If attaching to a crossarm, place the U-bolt in the CM225’s bottom
