(1) With toroidal core in the three line power supply cables (the three cables connected to R/L1, S/L2 and T/L3 must pass through a single toroidal core).
Example: TDK PN: PC40U120x160x20 ironxclube PN: U126x91x20-3F3. If the installation of the inverter is done inside the panel with attenuation of 10
dB in the frequency adjustable range [30; 50] mHz), the toroidal core is not necessary.
(2) For further details, contact WEG.
(3) Minimum operating frequency of 2.5 Hz.
