Tripod Installation Manual
Models CM110, CM115, CM120
1. 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. A durable
Tripod Tote Bag is available as an option.

4. Tripod Components
FIGURE 4-1 shows the tripod components packaged for shipment. The tripod
base is packaged with the mast, ground rod, lightning rod, and (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.
A diagram showing how to stow the components inside the tote bag is shown
in Appendix A.

5. Tripod Installation
5.1 Tripod Base
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. Contact local utility providers to
locate any buried utilities prior to installation.
WARNING
All three models of tripods use the same tripod base. Each leg is adjustable,
allowing the tr ipod to be adjusted for non-level terrain.
Prepare the area where the tripod will be installed. The tripod requires an area
approximately 7 feet 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 on end, and rotate the feet perpendicular to the legs.
Each leg has a slide collar and T-knob with a spring loaded pin that locks into
holes located on the underside of the leg as shown in FIGURE 5-1.
Extend each leg until the pin engages in a hole (depress the tab to disengage
the pin from a hole). With the legs extended, orient the tripod so that the open
channel of the tripod base faces north. The tripod is typically plumbed after
the mast has been installed, as described in Section 5.2, Mast.
