A4-1 Overview
When used in telecommunications, good grounding practices have some direct benefits that can help
users maximize system uptime as well as ensure the safety of those people working on the system.
Among these benefits are:
Protection of personnel from electric shock and fire hazards
Reduction of radiated and conducted electromagnetic susceptibility
Improved system tolerance to discharge of electrostatic energy and lightning interference
Minimized service interruptions and service damage
No practice or formula can completely eliminate the above risks, but interWAVE believes that good
grounding and bonding practices can significantly reduce the risk of many of these hazards. This
appendix includes a bibliography that contains several publications that are readily available and provide
detailed information on many aspects of grounding systems and their design, implementation,
measurement, and maintenance.
Please note that every telecommunication site is unique and must be evaluated accordingly. The
following information is provided for generic reference and educational purposes only. The grounding
plans and practices for a given site should be established and implemented only by trained profes-
sionals, working in accordance with local practices and regulations.
interWAVE strongly recommends that you install a Transtector Lightning
Arrestor or equivalent at the cable entry to the Ethernet, Power, and/or
DS-3 equipment structure.
