*With the use of the AS interface, terminal 44 provides an output voltage (24V, max. 60mA). In this case, no voltage sources may be connected to this
terminal!
NOTE
GND is a common reference potential for digital inputs and outputs and for the 24V supply of
the frequency inverter.
The labelling of the control terminal bar differs according to the SK 200E version.
