11.7. General
Coupling of the surge pulses is achieved by means of the coupling / decoupling network HSC 4-8. For additional protection of the
auxiliary equipment by reducing the residual voltage level the SPN 508N1 is used.
The HSC 4-8 design is based on the IEC 61000-4-5 (Ed 3.0: 2012) figure 11, IEC 61000-4-12 (Ed. 3) figure 10.
The HSC 4-8 allows the following couplings with separate input connectors:
- Surge and Ring wave pulses to data-lines
- Surge pulses to shield
- Burst pulses to shield
For an additional overvoltage protection of the AE port the SPN 508N2 can be used for limiting the residual voltage to approx. 10V.

11.8. Test methods for Surge and Ring Wave to high speed datalines
The IEC 61000-4-5 Ed.3 Surge standard shows in figure 11 the coupling network for testing high speed datalines.
The solution for coupling/decoupling is based on the existing methods of surge testing. There are two different Methods for testing
surge pulses on datalines.
