AHF 005/010
■
Mechanical installation
The encapsulation of the filters have an IP 20
rating. The modules can be mounted side by side
with 60mm (2,36 inches) clearance.
To other components and to the cabinet walls keep a
horizontal clearance of at least 70mm (2,76 inches) and
a vertical clearance of at least 150mm (5,91 inches).
For versions with bus bars (frame size E
– G) it is necessary to mount the added
covers to the connectors in order to
achieve the protection type IP 20.
■
Ventilation
The filters are cooled by means of air circulation.
Consequently, the air needs to be able to move freely
above and below the filter module. The efficiency
of the filter modules is greater than 0.98. When
installing a filter module in a panel or another enclosure,
ensure there is sufficient airflow though the enclosure
to limit heat rise in the enclosure.

NB!:
If other heat sources (e.g. Danfoss frequency
converters) are installed in an enclosure
with the harmonic filter AHF 0xx, this
heat generation must also be considered when
calculating required airflow
NB!:
If the cooling air is polluted (dust, dirt swirl,
grease, aggressive gas) the function of
the filter module may be impeded. Ensure
sufficient countermeasures, e.g. separate cooling air,
mounting of air filters, periodical cleaning.

Power wiring
Standard connection
Supply voltage must be connected to the terminals
X1.1, X1.2 and X1.3. The frequency converter supply
terminals L1, L2 and L3 must be connected to the
filter module terminals X2.1, X2.2 and X2.3.
Paralleling of FC’s
If several frequency converters are to be connected
to the harmonic filter, the connection is similar to the
standard connection - The supply terminals L1, L2 and
L3 of several frequency converters must be connected
to the filter module terminals X2.1, X2.2 and X2.3.
