SK ATX-POT
The Category 3D frequency inverter can be equipped with an ATEX-compliant 10 kΩ potentiometer
(SK ATX-POT), which can be used to setpoint (e.g. speed) adjustment on the device. The
potentiometer is used with an M20-M25 extension in one of the M25 cable glands. The selected
setpoint can be adjusted with a screwdriver. Due to the detachable screw closing cap, this component
complies with ATEX requirements. Permanent operation may only be carried out with the cap closed.
