3.3.4 Direction selection switch and potentiometer SK TIE4-SWT and SK TIE4-POT 
The  digital signals  R and  L of  the direction selector  switch  SK TIE4-SWT  (Part No.: 275274701)  can be 
applied directly to the corresponding digital inputs 1 and 2 of the frequency inverter. 
The potentiometer (0-10 V) SK TIE4-POT (Part No.: 275274700) can be evaluated via the analog inputs of 
the  frequency  inverter or  the  I/O  extension. Each  of the  modules  (control element)  is supplied  with a 
pre-assembled cable. This must be plugged into the connection plug of the relevant module. The open ends 
of the cable set must be wired to the terminal bar of the frequency inverter according to the table.  
Both modules have protection class IP66.
