5.6.2 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.
