5.4.4. Test Procedure
a) For EUT power supply:
The surge is applied to the EUT power supply terminals via the capacitive coupling network.
Decoupling networks are required in order to avoid possible adverse effects on equipment not
under test that may be powered by the same lines, and to provide sufficient decoupling impedance
to the surge wave. The power cord between the EUT and the coupling/decoupling networks was
shorter than 2 meters in length.
b) For test applied to unshielded un-symmetrically operated interconnection lines of EUT:
The surge was applied to the lines via the capacitive coupling. The coupling / decoupling networks
didn’t influence the specified functional conditions of the EUT. The interconnection line between the
EUT and the coupling/decoupling networks was shorter than 2 meters in length.
c) For test applied to unshielded symmetrically operated interconnection / telecommunication lines of
EUT:
The surge was applied to the lines via gas arrestors coupling. Test levels below the ignition point of
the coupling arrestor were not specified. The interconnection line between the EUT and the
coupling/decoupling networks was shorter than 2 meters in length.
