SIMODRIVE 611 Configuration Manual (PJU) -- 05/2008 Edition
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.

Note
If a fault current protective device is used on the line supply side of this
electronic device for protection in case of direct or indirect contact, only Type B
is permitted! Otherwise, another protection measure must be applied, such as
separating the electronic device from the environment through
double/reinforced insulation or separating the electronic device from the line
supply through a transformer.
