Electrical Installation
It is recommended not to use a PC power cable with a
ground plug when the PC is connected to the adjustable
frequency drive through a USB cable. It reduces the
ground potential difference, but does not eliminate all
potential differences due to the ground and shield
connected in the PC USB port.

9.6.5.2 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 additional harmonic
reduction devices, such as Danfoss AHF filters and 12–18-
pulse rectifiers, can be calculated.
MCT 31 can also be downloaded from www.danfoss.com/
BusinessAreas/DrivesSolutions/Softwaredownload/.
9.6.5.3 Harmonic Calculation Software
HCS is an advanced version of the harmonic calculation
tool. The calculated results are compared to relevant
norms and can be printed afterwards.
