6.6.6 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.

6.7 Safety

6.7.1 High Voltage Test

Carry out a high voltage test by short-circuiting terminals
U, V, W, L
380–500 V adjustable frequency drives and 2.525 kV DC for
525–690 V adjustable frequency drives for one second
between this short-circuit and the chassis.
WARNING
When running high voltage tests of the entire instal-
lation, interrupt line power and the motor connection if
the leakage currents are too high.

6.7.2 Grounding

The following basic issues need to be considered when
installing an adjustable frequency drive, so as to obtain
electromagnetic compatibility (EMC).

Safety grounding: The adjustable frequency drive
has a high leakage current and must be
grounded appropriately for safety reasons. Apply
local safety regulations.
High-frequency grounding: Keep the ground wire
connections as short as possible.
