8.6 Line harmonics filter
Clearances to other devices
Line harmonics filters are best installed as close as possible to the non-linear load. Ideally
they are mounted next to the converter inside the electrical cabinet.
In order to ensure sufficient air flow, keep a clearance of minimum 150 mm above and below
the filter to walls or other components.
It must be ensured that the environmental temperature is kept below 45 °C with appropriate
thermal management (e.g. cabinet cooling). Filter operation in environments with higher
temperatures require a temperature derating.
