Set point potentiometer
The category-3D SK 300E inverter can be equipped with a potentiometer meeting
ATEX standards which can be used to vary the set point (e.g. the speed) on the device.
Designation: Potentiometer ATEX22 - SK 300E
Part number: 075142000
The selected set point can be adjusted with a screwdriver. As far as the potentiometer
is concerned, it will meet ATEX requirements due to a sealing cap which can be
screwed on. For continuous operation the sealing cap must remain fixed.
Technical data:
Resistance value of the potentiometer: 10 kilo-ohms
For a potentiometer to be used with the SK 300E frequency inverter, the device must
always be equipped with a customer interface (Basic I/O or Standard I/O)!
