SIMODRIVE 611 Configuration Manual (PJU) – 02/2012 Edition
Line Supply Connection
7.1
Line supply connection conditions for line supply infeed
For technical data, refer to Chapter 6.4 and Tables 7-1/7-2.
SIMODRIVE infeed units are designed to be connected to line supplies with
compatibility level, Class 3 of electromagnetic environments in industrial plants
and systems according to IEC/DIN EN61000–2–4:2002.
When the EMC mounting/installation guidelines are complied with, noise immu-
nity values according to IEC/DIN EN61000–6–2 Electromagnetic Compatibility
(EMC) – Generic Standard, Noise Immunity/emission – Part 2: Industrial envi-
ronments (1999) are complied with.
The SIMODRIVE unit may be directly connected to TN line supplies with selec-
tively tripping, AC/DC–sensitive RCCBs as protective measure.
Upstream devices providing protection against hazardous leakage currents or
for fire protection (such as residual–current protective devices) must be univer-
sal current–sensitive in accordance with the requirements of DIN EN 50178. In
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.
