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.
