2.8.2 Details of the SK 2x0E control connections
The frequency inverter generates its own control voltage and provides this to Terminal 43.
With size 4 the connection terminals for an electro-mechanical brake are located on a 2-pole terminal block
which is separate from the control terminal strip (Terminal 79/80, see Section 2.7.4).
