Models CM110, CM115, CM120 General The CM110 (10 ft), CM115 (15 ft), and CM120 (20 ft) tripods are corrosion- resistant stainless steel instrument mounts that support the attachment of sensors, solar panels, and environmental enclosures. A guy kit is included with the CM115 and CM120 models, and is an option for the CM110.
(6) stakes. The ground rod clamp, lightning rod, and ground wires are enclosed in a bag. The guy kit (optional for the CM110), and tripod tote bag (optional) are packaged separately. The CM115 and CM120 tripods include additional mast sections.
Tripod Installation Manual Models CM110, CM115, CM120 FIGURE 4-1. Tripod components Tripod Installation Tripod Base WARNING Tripod installation near power lines is dangerous. The minimum safe recommended distance from overhead power lines is two times the height of the tripod and mast combined.
FIGURE 5-1. Tripod leg, slide collar components Mast The CM110, CM115, and CM120 tripods have one, two, or three mast sections respectively. The top mast section has a 48-in long insert with a series of holes that can be extended to lengthen the mast (FIGURE 5-2). Remove the bolt that secures the insert to the inside of the mast, and slide the insert out from the mast to see the different hole locations.
Tripod Installation Manual Models CM110, CM115, CM120 Insert Mast FIGURE 5-2. Tripod mast and insert The tripod base has two sets of right-angled holes for attaching the mast; typically the lower set is used (FIGURE 5-3A). The mast is attached to the base with a pin, and secured in the upright position with a locking bracket.
Tripod Installation Manual Models CM110, CM115, CM120 Right-Angled Hole Wire Retainer FIGURE 5-3. Mast attachment to tripod base Secure the mast in the upright position by installing the locking bracket (FIGURE 5-4A). Insert the top of the bracket into the notches in the tripod base, and using both thumbs, press the bracket into the body of the base until the lower tabs lock into position (FIGURE 5-4B).

Tripod Installation Manual Models CM110, CM115, CM120 Load End Dead End Phillips Screw Lever Hook FIGURE 5-7. Mechanical drawing of guy hook and case 5.3.1 Guy Duckbill Anchor Kits Duckbill anchors are recommended for areas subjected to higher winds. They allow the guy wires to be anchored at points beyond the feet, thereby increasing the rating of the tripod for higher winds.
Tripod Installation Manual Models CM110, CM115, CM120 It is important that the anchors be driven at the same angle as the guy wires. Insert the drive bar into the anchor body and drive the anchor into the ground using a sledgehammer until only the top half of the loop or metal ring remains above the ground.

Tripod Installation Manual Models CM110, CM115, CM120 Staking the Tripod Feet Six stakes are provided for securing the tripod feet to the ground. Drive two stakes through holes in each foot at an angle as shown in FIGURE 5-10. Stakes may not be adequate depending on soil structure, maximum wind speeds experienced at the site, mast height, or wind load from the instrumentation.
Tripod Installation Manual Models CM110, CM115, CM120 Tripod Grounding Place the clamp over the ground rod and drive the rod (close to the center of the tripod) using a sledgehammer or fence post driver. Strip 1/2 in. of insulation from both ends of the black 4 AWG ground wire. Insert one end of the ground wire between the clamp and ground rod and tighten the bolt on the clamp.
