WARNING! Do not install the drive with EMC filter options +E200 and +E202
connected to a system that the filter is not suitable for. This can cause danger,
or damage the drive.
WARNING! Do not install the drive with the ground-to-phase varistor
connected to a system that the varistor is not suitable for. If you do, the varistor
circuit can be damaged. See the drive hardware manual.
Note: With option +E201, remove EMC AC, EMC DC and VAR screws in for systems
other than TN-S if not removed at the factory. For more information, contact Demag.
Check the insulation of the input and motor cables and the
motor
Check the insulation of the input cable according to local regulations before you
connect it to the drive.
Check the insulation of the motor cable and motor when the cable is disconnected
from the drive, see figure
