Recommendation
SIEMENS selectively switching AC/DC-sensitive residual current protection devices in
accordance with EN 61009-1 of the 5SM series e.g. 5SM3646-4 or 5SM3646-4+5SW3300
with an auxiliary disconnector (1 NC contact / 1 NO contact) for a rated current of 63 A and
rated residual current of 0.3 A (see catalog "BETA Modular Installation Devices - ET B1").
Note
AC or pulse
-sensitive RCCBs are not suitable.

Overvoltage protection
Overvoltage category III must be ensured. If required, install a surge arrester with a voltage
protection level U
p
of maximum 6 kV on the line side of the converter.

Line filters
3.6.1
Description
Line filters have the task to attenuate conducted interference emission in the frequency
range according to the specifications of EMC legislation. They are mainly effective in the
frequency range from 150 kHz to 30 MHz; this is the range relevant to ensure compliance
with the appropriate standard.
In conjunction with a line filter and the associated line reactor, drive line-ups with S120
Combi 10 kW, 16 kW and 20 kW Power Modules and a maximum total cable length up to
175 m, fulfill Category C2 according to EN 61800-3. An EMC compliant design is always
assumed.
Note
The line filter is only suitable for direct connection to line supplies with grounded neutral
point. An isolating transformer with vector group "Dyn" and grounded neutral point must be
used when connecting to other line supplies. The line
filter and the control cabinet must be
connected to the isolating transformer neutral point through a low inductance connection.
