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 .
Frequency
