Notes on lightning protection
WARNING
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 can be protected by
a lightning protection potential equalization system.
When implementing your lightning protection concept, make sure you adhere to the VDE
0182 or IEC 62305 standard.
Suitable lightning conductors are available in the range of accessories of SIMATIC NET
Industrial WLAN:
Lightning protector LP798- 2N (order no. 6GK5798-2LP10-2AA6 is the most suitable version)
Lightning protector LP798-1N (order no. 6GK5798-2LP00-2AA6)
WARNING
Danger due to lightning strikes
Installing one of these lightning protectors between an antenna and a SCALANCE W-700 is
not adequate protection against a lightning strike. The LP798-2N and LP798-1N lightening
protectors only work within the framework of a comprehensive lightning protection concept.
If you have questions, ask a qualified specialist company.
