Special immunity for the signal level
14.10.1 Surge protection for the high-voltage area at the power plant
Surge protection (Phoenix Contact Order No.: 2905223 or comparable protection) must be implemented for power plant
applications when using signal connection types t (telecommunications area), h (high voltage area) or f (field) in accordance
with IEC/EN
61850-3 or signal connection types 3 (process area) and 4 (high voltage area) in accordance with EN
61000-6-5.
When using the digital signals, a relay (Phoenix Contact Order No.: 2900299 or a comparable relay) can be implemented.
14.10.2 Surge protection for signals in railway applications
Surge protection (Phoenix Contact Order No.: 2905223 or comparable protection) must be implemented for railway
applications when using signals in accordance with EN
62236-4 and EN
50121-4.
When using the digital signals, a relay (Phoenix Contact Order No.: 2900299 or a comparable relay) can be implemented.
14.10.3 Surge protection for devices in use in safety-related systems
Surge protection (Phoenix Contact Order No.: 2905223 or comparable protection) must be implemented for railway
applications when using signals in accordance with EN
61000-6-7 for devices provided to perform functions in safety-related
systems (functional safety) in industrial settings.
When using the digital signals, a relay (Phoenix Contact Order No.: 2900299 or a comparable relay) can be implemented.
