The SK 2x5E for Category 3D 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 removable
screw closing cap, this component complies with
ATEX requirements. Permanent operation may only
be carried out with the cap closed.
