ATTENTION!
Under extreme circumstances and depending on the quality of the network it may lead to
interferences caused by the machine. If necessary and in order to exclude retroactive
effects on the internal power supply system, the operator should install a line filter on
the machine. Therefore, at working places where lots of powerful consumers are
connected it might also be necessary to use a system for network compensation. Please
also request your electricity supplier for this purpose.
ATTENTION!
Frequency converter (drive regulator) might release the Fl protected switch of your
electrical supply. In order to avoid malfunction, you either need an Fl protected switch
sensitive for pulse current or AC/DC sensitive.
In case of malfunction or release of the FI protected switch, please check the installed type.
The following signs indicate if your machine is equipped with one of the FI protected switches
described above.

We recommend you to use an FI protected switch sensitive to AC/DC. FI protected switches
sensitive to AC/DC (RCCB, type B are adequate for 1-phase and 3-phase fed frequency con-
verters (driving regulator).
An FI protected switch type AC (only for alternating current) is not appropriate for frequency
converters. FI protected switches type AC are no longer used.
