Installing the CMM5
Ensure that you comply with standard local or national electrical and climbing procedures
when you install the CMM5.
WARNING!
Installing a CMM involves electrical power and can involve height and
exposure to RF (Radio Frequency) energy. To avoid personal injury,
know and follow applicable national and local safety regulations and
industry best practices, and follow the specific guidelines in this
document
Avoiding Hazards
Use simple precautions to protect staff and equipment. Hazards include exposure to RF
waves, lightning strikes, power lines, and power surges. This section specifically
recommends actions to abate these hazards.
Grounding Equipment
Effective lightning protection diverts lightning current safely to ground, Protective Earth
(PE) . It neither attracts nor prevents lightning strikes.
Grounding Infrastructure Equipment
To protect both your staff and your infrastructure equipment, implement lightning
protection as follows:
Observe all local and national codes that apply to grounding for lightning protection.
Before you install your modules, perform the following steps:
•
Engage a grounding professional if you have any questions on grounding.
•
Install lightning arrestors to transport lightning strikes away from equipment. For
example, install a lightning rod on a tower leg other than the leg to which you mount
your module.
•
Connect your lightning rod to ground.
•
Plan to use an appropriate surge suppressor on any Ethernet cable at the point where it
enters any building or structure.
Install your modules at least 2 feet (0.6 meters) below the tallest point on the tower, pole, or
roof.
