1) The control section of the frequency inverter is not supplied from the AS interface line. The required auxiliary voltage for this is generated
by the device itself.

Information
24 V DC / AS-Interface (SK 225E/ SK 235E, except -AUX, -AXB)
With the use of the yellow AS interface line:
– the supply voltage (26.5 - 31.6 V DC) for the use of the digital inputs or other external peripherals (e.g.
activators) can be obtained from terminals 44/40. The permissible total current for this is limited to
60 mA!
The terminal "44" is protected against short circuit. In case of an overload it will switch off by a thermal
fuse element. After a cooling time that depends on the ambient conditions, the fuse will reset.
– no voltage source may be connected to terminals 44/40,
– the frequency inverter is supplied via the yellow AS-i line.
