The Category 3D frequency inverter can be equipped with an ATEX-compliant potentiometer, which can be
used to adjust a setpoint (e.g. speed) 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 re-
movable screw closing cap, this component complies with ATEX requirements. Permanent operation may
only be carried out with the cap closed.
Frequency setpoint setting
with a screwdriver
Resistance of the potentiometer 10 kOhm
