The drive is suitable for use on a circuit capable of delivering not more than 100,000
rms symmetrical amperes at 600 V maximum when the input cable is protected with T
class fuses.

Power factor
Harmonics are below the limits defined in IEEE 519-2014, and G5/4. The drive complies
with IEC 61000-3-2, IEC 61000-3-4 and IEC 61000-3-12.
Harmonic distor-
tion
The table below shows typical values of the drive for short-circuit ratio (
I

/
I

) of 20 to
100. The values will be met if the supply network voltage is not distorted by other loads
and when the drive operates at nominal load.

V ≤ 690 V
Indicates the total magnitude of the voltage distortion. This value is defined
as the ratio (in %) of the harmonic voltage to the fundamental (non-harmonic)
voltage:
THDv
Indicates the total harmonic current distortion of the wave form. This value is
defined as the ratio (in %) of the harmonic current to the fundamental (non-
harmonic) current measured at a load point at the particular moment when the
measurement is taken:
