AHF 005/010
■
Overtemperature contactor
The Danfoss harmonic filter AHF 005 and AHF 010 is equipped with a galvanically isolated contactor that is
closed under normal operating conditions and open if the filter is overheated. This contactor must be used to
prevent damages to the filter caused by overtemperature as shown in the following example.
Example: Connect terminal A of the harmonic filter
to terminal 12 or 13 (voltage supply digital input,
24V) of the Danfoss adjustable frequency drive
and terminal B to terminal 27 (digital input "Coast
Inverse"); the adjustable frequency drive will let go of
the motor (coasting) and thereby unload the filter if an
overtemperature is detected.
NOTE
The maximum rating of the overtemperature
contactor is 250V AC and 10A.
