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.
