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. 

 

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, 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). 

 

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. 

 

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

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.
