and systems according to IEC/DIN EN61000–2–4:2002.
When the EMC mounting/installation guidelines are complied with, noise immu-

(EMC) – Generic Standard, Noise Immunity/emission – Part 2: Industrial envi-
ronments (1999) are complied with.
Direct connection
The SIMODRIVE unit may be directly connected to TN line supplies with selec-

the case of other residual–current protective devices, a transformer with sepa-
rate windings must be connected upstream of the converter for purposes of
decoupling.
