4.1.6 Over temperature contactor
The Danfoss harmonic filter AHF 005 and AHF 010 is equipped with a galvanic isolated contactor that is closed under normal operating conditions
and open if the filter is overheated. A controlled ramp down within 30 s is allowed with overheat damage of filter. This contactor must be used to
prevent damage to the filter caused by over temperature as shown in the following example.
Example: Connect terminal A of the harmonic filter to terminal 12 or13
(voltage supply digital input, 24V) of the Danfoss frequency converter and
terminal B to terminal 27 (digital input “Coast Inverse”) the frequency
converter will let go of the motor (coasting) and thereby unload the filter
if an over temperature is detected.
NB!
The maximum rating of the over temperature contactor is 250V AC and 10A.

*Power wiring used for connection of the filter AHF 005 and AHF 010 in enclosure size E, F and G must be terminated with cable lugs that can be attached
to the input and output bus bars terminals. This type of termination imposes no specifications of the minimum and maximum cable size suitable for
connection. Power terminal details regarding the bus bars can be found in the figures below.
