) 200/208/220/230/240 V AC 1-phase for 200 V AC drives
200/208/220/230/240 V AC 3-phase
for 200 V AC drives
380/400/415/440/460/480 V AC 3-phase for 400 V AC drives
±10% variation from converter nominal voltage is allowed as default.
Short-circuit capacity Maximum allowed prospective short-circuit current at the input power
connection as defined in IEC 60439-1 is 100 kA. The drive is suitable
for use in a circuit capable of delivering not more than 100 kA rms
symmetrical amperes at the drive maximum rated voltage.
Note : Use appropriate fuses or MMP’s to achieve 100 kA.
Frequency 50/60 Hz ± 5%, maximum rate of change 17%/s
Imbalance Max. ±3% of nominal phase to phase input voltage

motor cable length
R0: 30 m (100 ft), R1…R4: 50 m (165 ft)
With output chokes the motor cable length may be extended to 60 m
(195 ft) for R0 and 100 m (330 ft) for R1…R4.
To comply with the European EMC Directive, use the cable lengths
specified in the table below for 4 kHz switching frequency. The
lengths are given for using the drive with the internal EMC filter or an
optional external EMC filter.
