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 in-
ches).
Only vertical installation is allowed (mains terminal at
bottom).
For versions with bus bars (frame size E
– H) it is necessary to mount the added
covers to the connectors in order to ach-
ieve the protection type IP 20.

Ventilation

The filters are cooled by means of air circulation. Con-
sequently, the air needs to be able to move freely
above and below the filter module. The efficiency of

NB!
If other heat sources (e.g. Danfoss fre-
quency converters) are installed in an en-
closure with the harmonic filter AHF 0xx,
this heat generation must also be consid-
ered when calculating required airflow

Power wiring

Standard connection
Supply voltage must be connected to the terminals
X1.1, X1.2 and X1.3. The frequency converter supply

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 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, period-
ical cleaning.
