parallel to the sensor surface. Site the sensor to allow easy access for maintenance while ideally avoiding any obstructions or reflections above the plane of the sensing element. Mount the sensor such that a shadow or a reflection will not be cast on it at any time. Figure 6-1 (p. - Page 12 2. Secure the solar radiation sensor to the mounting bracket. Refer to Figure 6-2 (p. 9) to determine which mounting holes are used by the sensor. Visually inspect the leveling feet on the sensor (if present) to ensure all feet are in contact with the mounting bracket. Figure 6-2.
- Page 13 4. Secure the mounting bracket to the crossarm or the vertical pole using the hardware included with the mounting bracket. The CM225, CM255, and CM261 use one or two U-bolts, nuts, flat washers, and lock washers to mount the bracket (Figure 6-3 [p.
- Page 14 5. The CM256 and CM275 bracket (Figure 6-4 [p. 11]) use two set screws to secure the crossarm or the pole in the channel at the base of the bracket. For pyranometers mounted horizontally, ensure the mounting bracket is horizontal in two dimensions. For pyranometers to be mounted at an angle with the CM255 or CM256, set the mounting bracket angle to the desired angle prior to tightening the mounting hardware.
- Page 15 6. The CM226 uses two bolts, wing nuts, and a clamp piece to secure it to a crossarm or mast (Figure 6-5 [p. 12]). Figure 6-5. CM226 showing horizontal and vertical mount options Solar Radiation Sensor Mounts...
- Page 16 7. The CM266 can be mounted vertically or horizontally on a Unistrut. To install, insert the bolt through the front of the mounting plate and thread the Unistrut nut onto the bolt by two turns. Slide the Unistrut nut into the Unistrut, making sure the two tabs on the CM266 also slide into the Unistrut to lock its orientation.
