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 protectors are available in the range of accessories of SIMATIC NET

Industrial WLAN:

●

Lightning protector LP798-1N (order no. 6GK5798-2LP00-2AA6)

●

Lightning protector LP798-2N (order no. 6GK5798-2LP10-2AA6)

Note
We recommend that you use the maintenance-free lightning protector LP798-2N.

Exception:
When there is also DC power is 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.
