5.8 Earthing and Lightning Protection

Caution !

Correct earthing and a reliable lightning protection system are vital in order to pre-

vent damage to the ITC2100-NA.

Earthing and lightning are interrelated and have the following functions:

 Electrical earthing:

This term refers to the earthing conductor which safely dissipates any fault current, e.g.

from the housing, to the building wiring's equipotential bonding system.

 RF earthing:

This refers to discharge of RF energy with respect to ground. One example of RF earth-

ing relates to the shielding which prevents or reduces escape of RF radiation.

 Lightning conduction:

A good lightning protection system is indispensable for safe and reliable operation of a

communication system. This is closely linked to the building's equipotential bonding

system.

This manual does not provide comprehensive recommendations and directives for earthing

or lightning protection of communication systems. This information is summarised in rele-

vant publications of various manufacturers. Please refer to these publications if necessary.
