Step 2: Mounting
HFS harmonic filters are best installed as close as possible to the non-linear load. Ideally they are mounted next
to the rectifier or motor drive inside the electrical cabinet or control room. All HFS harmonic filters wall-mounting
installation.
Important:
In order to ensure sufficient air flow, keep a clearance of
min.150mm above and below the filter to walls or other
components. Additional work to access the device,
caused by not respected clearance distances, will be
accounted separately.
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.

Screw selection: LS Electric recommends zinc coated hex ribbed flange steel bolts. Respect filters weight for
appropriate choice of screws! Head diameters must not exceed these dimensions:
M6: d ≤14.2mm, M10: d ≤21.2mm
