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 protectors are available in the accessories (Page 14) of SIMATIC NET
Industrial WLAN.
Note
We recommend that you use the maintenance-free lightning protector LP798-2N.
Exception: When there is also DC power supplied via the antenna cable. In this case, only the
lightning protector LP798-1N can be used.
WARNING
Danger due to lightning strikes
Installing this lightning protector between an antenna and a SCALANCE W700 is not
adequate protection against a lightning strike. The LP798-1N lightening protector only works
within the framework of a comprehensive lightning protection concept. If you have questions,
ask a qualified specialist company.
Note
The requirements of EN61000-4-5, surge immunity tests on power supply lines, are met only
when a Blitzductor is used with 24 VDC:
