Technical data
WARNING! A drive of category C3 is not intended to be used on a low-voltage public
network which supplies domestic premises. Radio frequency interference is
expected if the drive is used on such a network.
Note: It is not allowed to install a drive with the internal EMC filter connected on IT
(ungrounded) systems. The supply network becomes connected to ground potential
through the EMC filter capacitors, which may cause danger or damage the drive.
Note: It is not allowed to install a drive with the internal EMC filter connected to a
corner grounded TN system as this would damage the drive.
