6. Installation

6.1 Tripod Installation

6.1.1 Tripod Base

FIGURE 5-1. 60-degree guy angle

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.

All three models of tripods use the same tripod base. Each leg is adjustable,
allowing the tripod 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 6-1.

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 6.1.2, Mast.

6.1.2 Mast

FIGURE 6-1. Tripod leg, slide collar components

The CM110, CM115, and CM120 tripods have one, two, or three mast sections
respectively. The top mast section has a 56-in long insert with a series of holes
that can be extended to lengthen the mast (FIGURE 6-2). 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. Slide the insert back into the mast,
aligning the appropriate holes of the insert with holes in the mast, and replace
the bolt.

Additional 56-in mast section(s) included with the CM115 and CM120 tripods
have a 16-in long insert that is used to connect the mast sections together.
Remove the bolt that secures the insert to the inside of the mast and extend the
insert 8 in; align the holes and replace the bolt. Attach additional mast sections
by sliding the bottom of the next mast section over the insert of a lower section,
aligning the holes and installing the bolt. Typically the bottom mast section is
attached to the tripod and tilted down to a horizontal position, and the
additional mast sections bolted to the bottom section.

FIGURE 6-2. 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 6-3A). The mast is attached to the
base with a pin, and secured in the upright position with a locking bracket.
Both the pin and the locking bracket are secured with a lanyard.

To attach the lower mast section, hold the mast upright and align the hole in the
bottom of the mast with the holes in the tripod base. Insert the pin through the
holes, and rotate the wire retainer over the end of the pin as shown in FIGURE
6-3B. The pin should be seated in the bottom of the hole when the mast is
upright. Lift the mast up so that the pin is in the upper end of the hole to allow
the mast to be tilted down to a horizontal position.

Secure the mast in the upright position by installing the locking bracket
(FIGURE 6-4A). 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 6-4B). Install the pin as shown in
FIGURE 6-4C. To remove the bracket, remove the pin and squeeze the lower
part of the bracket to disengage the tabs, then rotate the bracket out and up.

Plumb the tripod by adjusting the northeast and south facing legs. With a level
on the east side of the mast, adjust the northeast leg for plumb. With the level
on the south side of the mast, adjust the south leg for plumb.

6.1.3 Installing the Guy Kit

The CM115 and CM120 tripods include a guy kit; the guy kit is an option for
the CM110. With the mast tilted down in the horizontal position, install the
guy collar over the mast insert, and attach the guy wires as shown in FIGURE
6-5. Return the mast to the upright position and install the locking bracket.

FIGURE 6-5. Guy collar

On the end of each guy line is a case consisting of a hook, clamp, and lever
arm. Rotate the lever arm to the “open” position, and attach the hook to the
tripod leg as shown in FIGURE 6-6. Loosen the Phillips screw, and remove
the slack in the guy line by feeding the load end of the guy wire through the
wedge while pulling up on the dead end (FIGURE 6-7).

After the slack has been removed from the guy lines, tighten the Phillips
screws and rotate the lever arms to “closed” position to tension the guy lines
(FIGURE 6-6).

6.1.3.1 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.

Two duckbill anchor kits are offered for these lightweight tripods. The 19282
Guy Duckbill Standard Anchor Kit is for standard soils, and the 25699 Guy
Duckbill Heavy Duty Kit is for aggressive soils. Aggressive soils have:

• Resistivity less than 3000 ohm-cm

• pH less than 5

• Chloride greater than 1000 ppm

• Sulfate greater than 500 ppm

• Poor aeration

The 19282 and 25699 have their own drive bar. The 19282 also has three
duckbill anchors with a cable attached to each of them. At the end of the cable
is a loop for connecting the guy wires. The 25699 has a threaded rod attached
to each of the three duckbill anchors instead of the cable. At the end of the
threaded rod is a metal ring for connecting the guy wires.

The duckbill anchors are driven to the ground at a 60-degree guy angle as
shown in FIGURE 6-8. Locate the anchors on a 7.5-ft radius for the CM115,
or a 10-ft radius for the CM120 as shown in FIGURE 6-9. Specifications for
sustained wind speed and gust tolerance are given based on guy angle, and the
ability of the anchors to hold at least 400 lbf.

Duckbill anchors are not suitable for rocky or sandy soils; UTEYE
anchors should be considered for these types of soils.

12

Tripod Installation Manual Models CM110, CM115, CM120

WARNING

Drive Bar

Duckbill Anchor

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. Place a bar or highlift jack through the loop or metal ring
and jack the anchor up about four inches to rotate the anchor into the load-lock
position.

Failure to install and lock the anchor at the correct angle
will result in the anchor cable cutting through the soil
until the angles equalize, causing slack.

6.1.3.2 Lowering Mast after Attaching Guy Wires

Once the guy lines have been adjusted, the lever arms can be “opened” and the
guy hooks removed to allow the mast to be lowered to the horizontal position.

14

Tripod Installation Manual Models CM110, CM115, CM120

6.1.4 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 6-10.

Stakes may not be adequate depending on soil structure, maximum wind
speeds experienced at the site, mast height, or wind load from the
instrumentation. For questionable situations, additional stakes (pn 17049) or
even concrete footings for the tripod feet and guy anchors should be
considered.

FIGURE 6-10. Staking the tripod feet

Tripod Installation Manual Models CM110, CM115, CM120

6.1.5 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. Attach the other end of the ground wire to the lug on the tripod base as
shown in FIGURE 6-12.

FIGURE 6-11. Ground rod and clamp

• Slide the keyhole notches in the upper and lower corners of the –LM

bracket over the two extended Phillips head screws located on the tripod
base as shown in FIGURE 6-15B.

• Remove the washers, nuts, and U-bolt from the U-bolt bracket. Install the

bracket as shown in FIGURE 6-15C. Tighten the nuts on the U-bolt until
the lock washers are compressed.

• Route the 14 AWG wire from the ground lug on the bottom side of the

enclosure to the ground lug on the base of the tripod (FIGURE 6-15).
Strip 1/2 in. of insulation from each end of the wire. Insert wire ends into
the ground lugs and tighten.

6.2.4 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 in OD) or vertical pole (1.0 to 2.1 in OD).

The LI200X pyranometer and LI190SB quantum sensor mount to the CM225
via the LI200S leveling base (see FIGURE 6-19). 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.

The 18098 mounting stand provides a larger surface for mounting a user­supplied Eppley pyranometer.

CM230XL

6.2.5 CM230 and CM230XL Adjustable Angle Mounting Kits

The CM230 mounts an antenna (1.0 to 1.5 in OD) to a mast or vertical pipe
(1.3 to 2.1 in OD) as shown in FIGURE 6-20. The bracket allows the antenna
to be adjusted for different angles.

The CM230XL is similar to the CM230, but has a longer mounting arm (see
FIGURE 6-20). Its longer length places the antenna or sensor away from the
mast or pole.
