Notes on lightning protection
Danger due to lightning strikes
Antennas installed outdoors must be within the area covered by a lightning protection
system. Make sure that all conducting systems entering from outdoors are protected by
lightning protection electrical bonding.
When implementing your lightning protection concept, make sure you adhere to the
requirements of the VDE 0182 or IEC 62305 standards.
Suitable lightning protectors are available in the range of accessories of RUGGEDCOM. For
more information, contact Siemens Customer Support.
