CM300-Series Mounting Poles
1. Overview
The CM300-series mounting poles provide a stainless steel 1.5 IPS vertical
pole for mounting sensors, enclosures, or other instrumentation. Pole length is
58 cm (23 in), 119 cm (47 in), or 142 cm (56 in) for the CM300, CM305, and
CM310 models, respectively.
Mounting poles are placed directly into a concrete foundation, attached to a
concrete foundation with the Pedestal J-Bolt Kit option, or are self-supporting
with the Pedestal Leg options (FIGURES 1-1, 3-1, 3-4, 3-6). A vinyl cap
prevents precipitation from entering through the top of the pole.

(2) 1/2-inch combination wrench
(2) 3/4-inch combination wrench
Large Phillips screwdriver
Torpedo level

3.2 CM300-Series Mounting Pole in Concrete Foundation
For permanent installations, CM300-series poles are installed in a concrete
foundation. Dig a hole 15 to 20 cm (6 to 8 in) in diameter by 60 cm (24 in)
deep (or below frost level). Place the pole in the center of the hole. Fill the hole
with concrete, and plumb the pole with a level.

3.3 CM300-Series Mounting Pole with Pedestal J-Bolt Kit
A CM300-series pole with the Pedestal J-Bolt Kit option is used for permanent
installations where there is a need to periodically plumb the pole. J-bolts are
installed in a concrete foundation by using the template provided with the kit.
The template positions the J-bolts in the 15.25 cm (6 in) diameter circle
required by the pedestal.
Construct a form 36 cm (14 in) square (inside dimensions) from 38 x 89 mm
(2 x 4 in) precut lumber. Cut two additional 46 cm (18 in) boards from the 38 x
89 mm (2 x 4 in) precut lumber.
Dig a hole 36 x 36 x 60 cm (14 x 14 x 24 in) deep. Depth should exceed typical
frost level. Center, and level the form over the hole.

FIGURE 3-2. Base Assembly
Thread two nuts onto each J-bolt, leaving 2.5 cm (1 in) of thread visible
between the nuts and end of the J-bolt. Attach the J-bolts to the template with
another nut. Angle each J-bolt so it points away from the center of the
template.
Place the two 46 cm (18 in) pieces of lumber over the form, leaving room for
the J-bolts. Lower the J-bolts into the hole until the template comes to rest on
the 46 cm (18 in) boards. Optional: Use wood screws to anchor the template to
the two 46 cm (18 in) boards.
Fill the hole and form with concrete.
FIGURE 3-3. Base Embedded in Concrete
Remove the template after the concrete has cured. Leave the two nuts below
the template on each J-bolt in place. Insert the pole into the pedestal, and
tighten the six bolts evenly.

Place a flat washer on each J-bolt, resting it on the two nuts already there.
Place the pedestal over the J-bolts and install a flat washer, split washer, and
nut on each J-bolt — do not tighten the nuts at this time.
Adjust the lower nuts on each J-bolt to plumb the pole. “Lock” the lower nuts
together by using two wrenches. Tighten the upper nuts to secure the pedestal
to the J-bolts.

3.4 CM300-Series Mounting Pole with Pedestal Legs
A CM300-series pole with a Pedestal Leg option is used for temporary
installations or for applications where a concrete foundation is not an option.
The 58 cm (23 in) Pedestal Legs are adequate for most applications. The 99 cm
(39 in) Pedestal Legs provide additional stability for applications where the
feet cannot be secured (for example, to the surface of a roof), for extended
poles, or for locations with high winds.
Each leg attaches to the pedestal base with an adjustable bolt and quick release
pin. The pedestal base has a set of six holes for each leg. The angle of the legs,
and resultant pedestal height, is determined by which hole the quick release pin
is placed through (see TABLE 3-1).

Place the pole into the base and tighten the six bolts evenly. For additional
stability, the feet are spiked to the ground using (3) ground spikes, or secured
with user-supplied anchors through the holes in the feet.

3.5 Grounding
The Tripod Grounding Kit for Stainless-Steel CM110-Series Tripods may be
used to provide an earth ground for the pedestal and associated
instrumentation. Attach the earth and enclosure ground wires to the lug on the
pedestal base as shown in FIGURE 3-6.The tripod grounding kit also includes
a lightning rod for instances where a lightning rod is needed.

Safety
DANGER — MANY HAZARDS ARE ASSOCIATED WITH INSTALLING, USING, MAINTAINING, AND WORKING ON OR AROUND
TRIPODS, TOWERS, AND ANY ATTACHMENTS TO TRIPODS AND TOWERS SUCH AS SENSORS, CROSSARMS, ENCLOSURES,
ANTENNAS, ETC. FAILURE TO PROPERLY AND COMPLETELY ASSEMBLE, INSTALL, OPERATE, USE, AND MAINTAIN TRIPODS,
TOWERS, AND ATTACHMENTS, AND FAILURE TO HEED WARNINGS, INCREASES THE RISK OF DEATH, ACCIDENT, SERIOUS
INJURY, PROPERTY DAMAGE, AND PRODUCT FAILURE. TAKE ALL REASONABLE PRECAUTIONS TO AVOID THESE HAZARDS.
CHECK WITH YOUR ORGANIZATION'S SAFETY COORDINATOR (OR POLICY) FOR PROCEDURES AND REQUIRED PROTECTIVE
EQUIPMENT PRIOR TO PERFORMING ANY WORK.
Use tripods, towers, and attachments to tripods and towers only for purposes for which they are designed. Do not exceed design limits. Be familiar and
comply with all instructions provided in product manuals. Manuals are available at www.campbellsci.com. You are responsible for conformance with
governing codes and regulations, including safety regulations, and the integrity and location of structures or land to which towers, tripods, and any
attachments are attached. Installation sites should be evaluated and approved by a qualified engineer. If questions or concerns arise regarding installation,
use, or maintenance of tripods, towers, attachments, or electrical connections, consult with a licensed and qualified engineer or electrician.
General
•Protect from over-voltage.
•Protect electrical equipment from water.
•Protect from electrostatic discharge (ESD).
•Protect from lightning.
•Prior to performing site or installation work, obtain required approvals and permits. Comply with all
governing structure-height regulations, such as those of the FAA in the USA.
•Use only qualified personnel for installation, use, and maintenance of tripods and towers, and any
attachments to tripods and towers. The use of licensed and qualified contractors is highly recommended.
•Read all applicable instructions carefully and understand procedures thoroughly before beginning work.
•Wear a hardhat and eye protection, and take other appropriate safety precautions while working on or
around tripods and towers.
•Do not climb tripods or towers at any time, and prohibit climbing by other persons. Take reasonable
precautions to secure tripod and tower sites from trespassers.
•Use only manufacturer recommended parts, materials, and tools.
Utility and Electrical
•You can be killed or sustain serious bodily injury if the tripod, tower, or attachments you are installing,
constructing, using, or maintaining, or a tool, stake, or anchor, come in contact with overhead or
underground utility lines.
•Maintain a distance of at least one-and-one-half times structure height, 20 feet, or the distance required by
applicable law, whichever is greater, between overhead utility lines and the structure (tripod, tower,
attachments, or tools).
•Prior to performing site or installation work, inform all utility companies and have all underground utilities
marked.
•Comply with all electrical codes. Electrical equipment and related grounding devices should be installed by a
licensed and qualified electrician.
Elevated Work and Weather
•Exercise extreme caution when performing elevated work.
•Use appropriate equipment and safety practices.
•During installation and maintenance, keep tower and tripod sites clear of un-trained or non-essential
personnel. Take precautions to prevent elevated tools and objects from dropping.
•Do not perform any work in inclement weather, including wind, rain, snow, lightning, etc.
Maintenance
•Periodically (at least yearly) check for wear and damage, including corrosion, stress cracks, frayed cables,
loose cable clamps, cable tightness, etc. and take necessary corrective actions.
•Periodically (at least yearly) check electrical ground connections.
Internal Battery
•Be aware of fire, explosion, and severe-burn hazards.
•Misuse or improper installation of the internal lithium battery can cause severe injury.
•Do not recharge, disassemble, heat above 100 °C (212 °F), solder directly to the cell, incinerate, or expose
contents to water. Dispose of spent batteries properly.
WHILE EVERY ATTEMPT IS MADE TO EMBODY THE HIGHEST DEGREE OF SAFETY IN ALL CAMPBELL SCIENTIFIC PRODUCTS, THE
CUSTOMER ASSUMES ALL RISK FROM ANY INJURY RESULTING FROM IMPROPER INSTALLATION, USE, OR MAINTENANCE OF
