MCT 31
The MCT 31 harmonic calculation PC tool enables easy estimation of the harmonic distortion in a
given application. Both the harmonic distortion of Danfoss adjustable frequency drives as well as
non-Danfoss adjustable frequency drives with different additional harmonic reduction devices,
such as Danfoss AHF filters and 12-18-pulse rectifiers, can be calculated.

2.15 kV DC for one second between this short circuit and the chassis.
5.6.2. Safety Ground Connection
The adjustable frequency drive has a high leakage current and must be grounded appropriately
for safety reasons according to EN 50178.
