Fig. 8-6: Connection screw for internal EMC filter
Internal EMC filter must be disconnected in isolated neutral power system (e.g.,
IT-Net). Otherwise, the system will be grounded via the capacitor of the EMC fil-
ter, which may lead to danger or damage to the frequency converter. The con-
nection screw for the internal EMC filter as shown in the figure above is located
at the side of the frequency converter.
With the internal EMC filter disconnected, the specified EMC per-
formance of the frequency converter cannot be reached.
