AHF 005/010 Operating Instructions
4 Installation
4.1 Installation
4.1.1 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).
Only vertical installation is allowed (mains terminal at bottom).
For versions with bus bars (frame size E – H) it is nec-
essary to mount the added covers to the connectors in
order to achieve the protection type IP 20.
4.1.2 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.
