4.1.5 Fuses
In order to protect the installation against electrical and fire hazards, all filters in an installation must be short-circuited and over-current protected
according to national/international regulations. The filter must be protected against short-circuit and overload to avoid electrical or fire hazard and to
protect cables and filter from overheating. Danfoss recommends using fuses mentioned below to protect service personnel and equipment in case of an
internal failure in the filter.
Both filter and drive have to be connected against overload. If several frequency converters are to be connected to the one common harmonic filter, it
might be necessary to install fuses in front of both filter and drives.
In case of paralleled filter installation it might be necessary to install filters in front of each drive as well as in front of the entire installation to protect
both individual filters and drives.
