Test to shielded line is adapted from the figure 16 

where the surge is applied direct to the shield of the 

data cable.

Coupling direct to high speed lines 

Test with coupling direct to the data-lines is based to 

figure 11 of IEC 61000-4-5 standard. The surge is 

applied direct to unshielded symmetrical high-speed 

data-lines. For decoupling and protection, it is 

necessary to use separate devices of the HSC 4-8 

assembly.

Test setup 

 

The SPN 508N1 protects the auxiliary equipment with a residual  

voltage of less than 10V.  

 

Generator output plugs 

The Surge and Ringwave output plugs are 

located at the rear side of the impulse 

generator. The surge generator impedance 

is 2 

Ω. The additional impedance is inside 

the HSC 4-8. 
Surge, Ringwave: 

Output HV –COM on rearside of the 

generator with direct coupling.

Figure 68 - Burst pulse output 

 

Grounding

:   The generator and the used devices of the HSC 4-8 assembly must be grounded properly to the reference 

ground. 

 

11.10.  Surge test to shielded datalines 

This test will couple the surge pulse to the shield of a shielded RJ24 data-cable. The cable to the EUT must be mandatory a 

shielded cable.
