The internal coupling network is designed for mains frequency 50 Hz / 60 Hz.
When L – N coupling is selected an additional current of approx. 1.5 A flows, caused by the
18 F coupling capacitor and the pulse forming network. A similar current appears during the
couplings to PE.
Tests with 400 Hz mains frequency destroy the coupling network. An external coupling

network is recommended with inductors and capacitors matched to the 400 Hz mains
frequency.
