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 frequency converters as well as non-Danfoss frequency converters with different additional harmonic reduction devices, such as Danfoss AHF
filters and 12-18-pulse rectifiers, can be calculated.

5.6 Safety
5.6.1 High Voltage Test
Carry out a high voltage test by short-circuiting terminals U, V, W, L
1
, L
2
and L
3
. Energize maximum 2.15 kV DC for 380-500V frequency converters and
2.525 kV DC for 525-690V frequency converters for one second between this short-circuit and the chassis.
When running high voltage tests of the entire installation, interrupt the mains and motor connection if the leakage currents are too
high.
5.6.2 Safety Earth Connection
The frequency converter has a high leakage current and must be earthed appropriately for safety reasons acording to EN 50178.
The earth leakage current from the frequency converter exceeds 3.5 mA. To ensure a good mechanical connection from the earth
cable to the earth connection (terminal 95), the cable cross-section must be at least 10 mm
2
or 2 rated earth wires terminated sepa-
rately.
