All parameter settings are now transferred to the frequency converter.
A separate manual for PC-based Configuration Tool MCT 10 is available.
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 con-
verters with different additional harmonic reduction devices, such as
Danfoss AHF filters and 12-18-pulse rectifiers, can be calculated.
MCT 31 can also be downloaded from the Danfoss Internet:

5.6. Safety

5.6.1. High Voltage Test
Carry out a high voltage test by short-circuiting terminals U, V, W, L
and the chassis.
NB!
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 mm2 or 2 rated earth wires terminated sepa-
rately.
