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

l

Protect from over-voltage.

l

Protect electrical equipment from water.

l

Protect from electrostatic discharge (ESD).

l

Protect from lightning.

l

Prior to performing site or installation work, obtain required approvals and permits. Comply with all governing structure-height regulations.

l

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.

l

Read all applicable instructions carefully and understand procedures thoroughly before beginning work.

l

Wear a hardhat and eye protection, and take other appropriate safety precautions while working on or around tripods and towers.

l

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.

l

Use only manufacturer recommended parts, materials, and tools.

Utility and Electrical

l

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.

l

Maintain a distance of at least one-and-one-half times structure height, 6 meters (20 feet), or the distance required by applicable law,

whichever is greater, between overhead utility lines and the structure (tripod, tower, attachments, or tools).

l

Prior to performing site or installation work, inform all utility companies and have all underground utilities marked.

l

Comply with all electrical codes. Electrical equipment and related grounding devices should be installed by a licensed and qualified

electrician.

l

Only use power sources approved for use in the country of installation to power Campbell Scientific devices.

Elevated Work and Weather

l

Exercise extreme caution when performing elevated work.

l

Use appropriate equipment and safety practices.

l

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.

l

Do not perform any work in inclement weather, including wind, rain, snow, lightning, etc.

Maintenance

l

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.

l

Periodically (at least yearly) check electrical ground connections.

Internal Battery

l

Be aware of fire, explosion, and severe-burn hazards.

l

Misuse or improper installation of the internal lithium battery can cause severe injury.

l

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 TRIPODS, TOWERS, OR

ATTACHMENTS TO TRIPODS AND TOWERS SUCH AS SENSORS, CROSSARMS, ENCLOSURES, ANTENNAS, ETC.
