The cable should be as short as possible, and the cable cross section should correspond to the 
national/international regulations so that the voltage supply at the rectifier does not deviate 
from the rated voltage by more than ±2 %.
If the drum motor with electromagnetic brake is used at an ambient temperature below +5 °C, 
a special oil must be used. In case of doubt, contact Interroll.
The electromagnetic brake is a pure holding brake and should not be used for positioning or 
braking the motor. Positioning applications should be implemented with a frequency inverter in 
conjunction with an encoder integrated in the motor. Braking applications should be implemented 
with a frequency inverter.
