Selection of line filter to reduce line-conducted interference
To reduce line-conducted interference, use the appropriate line filter for each frequency inverter.
The table below show you a list of the available line filters for your Hitachi frequency inverter.
The all line filters are built in the so-called footprint style, are fitted behind the respective
frequency inverter, and thus require no additional space for installation. These filters are intended
for installation in switch cabinets as standard.
Vertical mounting next to the frequency inverter is also possible.
Note:
All filters are designed for 50/60Hz.
