EMC filter
A drive with the internal EMC filter connected can be installed to a symmetrically
grounded TN-S system. If you install the drive to another system, you may need to
disconnect the EMC filter. See section Checking the compatibility with IT
(ungrounded), corner-grounded delta, midpoint-grounded delta, and TT systems (for
IEC) in ACQ580-01 (0.75 to 250 kW, 1.0 to 350 hp) hardware manual
(3AXD50000044862 [English]).
WARNING! Do not install a drive with the EMC filter connected to a system
that the filter is not suitable for. This can cause danger, or damage the drive.
Note: When the internal EMC filter is disconnected, the EMC compatibility of the
drive is considerably reduced. See section EMC compatibility and motor cable length
