lightning arrester are as follows: Port protective unit–single port, maximum discharge current (8/20
μ
s
waveform): 5 kA, output voltage (10/700
μ
s waveform): core-core < 40 V, core-ground < 600 V.
For the installation of a port lightning arrester, refer to Chapter 4 “Installing the Firewall.”
Power Lightning Arrester (Optional)
