lightning arrester can be installed on the device. The specifications for the port 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.
Note:
For the installation of the port lightning arrester, refer to section 5.6 “Installing a Port
Lightning Arrester (Optional)” in Chapter 5 “Installing the Router”.
