CM106K Tripod 1. Cautionary Statements 1.1 Site Selection • Select a safe site to install the tripod. • The distance between any power lines and the installation site should be at least one and one-half times the height of the tripod. Make the distance even greater, if at all possible. Since all overhead power lines look somewhat alike, consider them all dangerous and stay well away from them. • If you have power lines or buried utilities in the area, call your local utility providers for assistance.

CM106K Tripod Prepare the area where the tripod will be installed. The tripod requires an area approximately 11 ft (3.4 m) in diameter. Natural vegetation and the ground surface should be disturbed as little as possible, but brush and tall weeds should be removed. Stand the tripod base up on end, and rotate the feet perpendicular to the legs. Each leg has a clamp bracket with a bolt that locks the leg in place when tightened. 2.2.
CM106K Tripod 2.3 Mast Slide the mast into the tripod base orienting the end with the hole upwards, making sure that it extends below the lower bolts and rests on the tripod body tabs. Tighten the six 5/16-18 x 2.25” bolts to secure the mast. Plumb the tripod by adjusting the northeast and south facing legs (use the downhill leg and one of the uphill legs when the tripod is installed on a slope). With a level on the East side of the mast, adjust the Northeast leg for plumb.
CM106K Tripod 2.4 Installing the Optional Guy Kit PN 27117 CM106 Guy Kit can be ordered separately for areas that experience high wind speeds (Section 4). Install the guy bracket to the mast as shown in Figure 2-3. Attach the three guy wires to the guy collar and slide the collar over the mast so that the collar butts against the bracket. Guy Collar Guy Wire Guy Bracket FIGURE 2-3. Guy collar On the end of each guy line is a case and hardware to attach to the turnbuckles.

CM106K Tripod 2.5 Staking the Tripod Feet For additional stability, the tripod can be staked to the ground using (3) PN 17049 ground spikes, or secured with user-supplied anchors through the holes in the feet. Drive the spike at an angle through the hole in each foot. Spikes may not be adequate depending on soil structure, maximum wind speeds experienced at the site, mast height, or wind load from the instrumentation.
CM106K Tripod 2.6 Tripod Grounding The tripod must be properly grounded using a user-supplied grounding rod. Place the clamp over the ground rod and drive the rod (close to the center of the tripod) using a sledge hammer or fence post driver. Strip 1/2” [12.7 mm] inch of insulation from both ends of a 4 AWG ground wire. Insert one end of the ground wire between the clamp and ground rod and tighten the bolt on the clamp.
CM106K Tripod Mount the lightning rod and clamp to the tripod mast with pointed tip up, and notch at bottom, as shown in Figure 2-7. FIGURE 2-7.
CM106K Tripod 2.7 Crossarm Attachment Attach the CM202 (2 ft, 0.6m), CM204 (4 ft, 1.2m), or CM206 (6 ft, 1.8m) crossarm to the tripod mast as shown in Figure 2-8. For wind sensors, the crossarm should be approximately 103 inches above the ground. Typically the crossarm is oriented East/West for wind sensors, North/South for pyranometers. CM200 Series Crossarm Tripod Mast FIGURE 2-8. CM204 Crossarm 2.
CM106K Tripod Route the 14 AWG wire from the grounding lug on the bottom side of the enclosure to the grounding lug on the base of the tripod (Figure 2-6). Strip 1/2” [12.7 mm] of insulation from each end of the wire. Insert wire ends into the grounding lugs and tighten. U-Bolt –MM Bracket FIGURE 2-9. Enclosure with the –MM Bracket 2.8.
CM106K Tripod Route the 14 AWG wire from the grounding lug on the bottom side of the enclosure to the grounding lug on the base of the tripod (Figure 2-6). Strip 1/2” of insulation from each end of the wire. Insert wire ends into the grounding lugs and tighten. FIGURE 2-10.

CM106K Tripod 7.2 CM216 Mast Mounting Kit The CM216 attaches to the top of the mast, and provides a 3/4” or 1” mounting pipe (1.05” or 1.32” OD) that extends 4” above the mast, as shown in Figure 7-2. CM216 FIGURE 7-2.
CM106K Tripod 7.3 CM220 Right Angle Mounting Kit The CM220 attaches a vertical pipe (1.0 – 1.5” OD) to the CM200 series crossarms or horizontal pipe (1.0 – 1.5” OD) as shown in Figure 7-3. CM220 CM220 FIGURE 7-3.
CM106K Tripod 7.4 CM225 and 18098 Pyranometer Mounting Stand The CM225 is used to attach a pyranometer or quantum sensor to a horizontal pipe (1.0 to 2.1” OD) or vertical pole (1.0 to 2.1” OD). The LI200X pyranometer and LI190SB quantum sensor mount to the CM225 via the LI200S leveling base (see Figure 7-4). The CS300 pyranometer mounts to the CM225 via the 18356 leveling base. The CMP3 and LP02 pyranometers include their own bubble level and leveling screws allowing them to mount directly to the CM225.
CM106K Tripod 7.5 CM230 Adjustable Angle Mounting Kit The CM230 mounts an antenna (1.0 – 1.5” OD) to a mast or vertical pipe (1.3 – 2.1” OD) as shown in Figure 7-5. The bracket allows the antenna to be adjusted for different angles. CM230 FIGURE 7-5.
CM106K Tripod 7.6 CM235 Magnetic Mounting Stand The CM235 provides a 3.5” (8.8 cm) square platform for mounting magnetic base antennas. The CM235 attaches to horizontal or vertical pipes (1.0 – 2.1” OD) as shown in Figure 7-6. FIGURE 7-6.
CM106K Tripod 7.7 RM Young Gill Radiation Shields RM Young Gill Radiation Shields are used to house and attach temperature and relative humidity sensors to the tripod mast (1.0 – 2.1” OD) or crossarm as shown in Figure 7-7. Radiation shields ship with the U-bolt configured for attachment to a vertical pipe. To attach the radiation shield to a horizontal pipe, the U-bolt and plastic V-block must be moved to the other set of holes. FIGURE 7-7.
