Note
Converters, frame size FSC
At the time the manual was being created, it was not clear as to whether converters with frame
size FSC can be connected with other frame sizes.
As a consequence, when converters with frame size FSC become available, carefully observe
the product information or manuals on the S210 in the Internet.

Additional external braking resistors for the DC link coupling
The entire braking power of all converters coupled in a group is always available for braking.
If you require an external braking resistor for your system in spite of a DC link coupling, then you
must connect this to the converter with the highest power rating. If an additional external
braking resistor is required, then this must be connected to the converter with the second
highest power rating – and so on.
Additional information
Special features for converters with a 3 AC 200 V ... 240 V line connection
When this manual was prepared, the DC link coupling was only permissible for converters
within the same frame size. Otherwise, the above mentioned points apply.
When connected to 3 AC 200 V ... 240 V line supplies, also refer to the following Section:
