) 200…240 V AC +/-10%, 3-phase
380…500 V AC +10%/-15%, 3-phase
Network type Grounded (TN, TT) or ungrounded (IT).
Note: If the installation site is higher than 2000 m (6600 ft) above sea level,
connection of the drive to an ungrounded (IT) or corner-grounded delta
network is not allowed.

100 kA when protected by fuses given in the Supply cable fuses on
page 118.
Frames R1 and R2: Thermal dimensioning of the DC capacitors is based
on max. 5 kA short-circuit current. An input choke should be used to
achieve 100 kA.
