Test to shielded line is adapted from the figure 16
where the surge is applied direct to the shield of the
data cable.
Figure 65 - Coupling to Shielded Lines
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.

11.9. 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 67 - Surge output on rearside
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.
