2.8.3 Details of the SK 2x5E control connections
Control voltage 24V external! Terminal 44. If the frequency inverter is not equipped with an optional mains
unit it must be supplied with an external 24V voltage.
For devices where the AS interface is used (SK 225E and SK 235E), the control voltage supply must be
provided via the yellow AS interface cable. In this case however, the frequency inverter must not have an
additional supply via Terminal 44 in order to prevent damage to the mains unit or the AS interface bus.
