3.5.3 PotentiometerBox SK TU4-POT-…
The PotentiometerBox SK TU4-POT enables simple motor speed and direction control via a series SK 2x5E
frequency inverter. LEDs on the enable keys indicate the selected enable direction. In addition, with the
integrated mains unit, the 24V control voltage for the FI is produced from the mains voltage
(115V/230V/380V/500V). With this, a separate external 24V control voltage is not necessary.

NOTE
Use of the SK TU4-POT on the SK 2x0E is not permissible!
A mains unit is integrated into the SK 2x0E inverter models, so that no external 24V DC is
required.
