Filtering
No filters are needed for the converter to function. However, under some circumstances, filters may be
needed on the input or the output side to comply with EMC regulations.
If you have any queries about filter design, please ask for the description entitled Baumüller Filters for
Network Applications, BFN.
Filter assembly
y Mount the filter directly next to the converter. With lines that are more than 30 cm long, you must
screen the mains line between the converter and the filter (frame-ground on both sides).
y Physically separate the filter's input and output lines by more than 30 cm.
y Make a broad connection between the filter housing and frame ground.
Discharge currents
Due to the principle of operation, parasitic capacities in the filter, the mains unit, the motor cable and the
motor winding cause discharge currents of around 100 mA and higher.
This means that converters with earth leakage circuit-breakers may be incompatible!
In this context, you should observe the safety information in provisional standard EN 50178:1994 Sec-
tion 5.2.11.2.
