6 Safety Instructions
 Safety instructions for harmonic filters
1. PIHF harmonic filter is matched with the frequency converter, which can only
be mounted at the power inlet of the frequency converter.
2. The power of the selected filter shall be matched with that of the frequency
converter as far as possible, to obtain the best filtering effect. If not
matched, the filter with the higher power can be used for that with the lower
power, but the filtering effect may be reduced.
3. A single PIHF filter can be used to power multiple frequency converters, but
the total load shall not exceed the rated power value of PIHF filter.
4. The reactor in the filter is a heat generating device. It shall be mounted to
keep a heat dissipation space of at least 150mm around the filter. When two
filters are mounted in parallel, the distance between the filters shall be at
least 200mm.
5. The capacitor in the filter is a temperature-sensitive device, of which the
ambient temperature shall be kept below 50 ℃ .
6. A reliable ground wire shall be connected for mounting according to the
wiring instructions in the circuit diagram.
7. If the harmonic filter needs to be operated, first measure whether there is
any residual dangerous voltage on the incoming and outgoing terminals of
the filter.
Grounding

Warning! Ignoring the following instructions may cause personal injury
or death, and increase electromagnetic interference and equipment
damage.
In any case, the harmonic filter, drive and its connecting equipment shall be
grounded to ensure personal safety and reduce electromagnetic radiation and
interference.
The size of the grounding conductor shall meet the requirements of local safety
regulations.
