2.3 UB line filter up to 22kW (accessory)
An additional external line filter can be installed into the line supply of the frequency inverter to maintain the increased noise
suppression level (class B as per EN 55011).
When connecting the line filter, comply with Chapter 2.9 "Wiring guidelines" and 8.3 "EMC". In particular, ensure that the pulse
frequency is set to the default value (P504 = 4/6kHz) and that the maximum motor cable length (30m) is not exceeded and a
shielded motor cable is used.
Mains connection is by means of screw connections at the lower end of the filter. Inverter connection is by means of a fixed
cable of a suitable length (235-385mm).
The filter should be located as close as possible to the inverter; it can be used as a substructure or Book Size component.
