A.5.5
Application example for protection of ET 200iSP from overvoltages
Application example
The following figure shows the necessary measures for two networked ET 200iSP. Based on
agreement, all cables and wires from lightning protection zone 0
B
and higher, i.e. lightning
component currents, must be excluded.
In the application example, the cable and wire systems are unshielded.
