Description

In conjunction with line reactors and a consequential implementation of the plant/system
configuration according to the EMC guidelines (Order No.: 6FC5297-☐AD30-0AP☐), line
filters limit the cable-borne noise and disturbances emitted from power modules to
permissible values for the industrial environment at the installation location.
Note
All PM340 Power Modules are equipped with an integrated line filter.
Frame size A, 400V, is an exception; in this case, an external line filter must be used.

Safety information

Danger
Line filters are suitable for direct connection to TN line supplies with grounded neutral
conductor.
Caution
The cooling clearances of 100 mm above and below the components must be observed.
This prevents thermal overload of the line filter.
Caution
The terminals must be correctly connected:
• Incoming line cable to LINE/NETZ L1, L2, L3
• Outgoing cable to the line reactor to LOAD/LAST L1', L2', L3'
Non-observance may damage the line filter
Caution
Using line filters not released by Siemens AG for SINAMICS can lead to line reactions that
can damage or destroy other loads powered from the network.
