The choke has to be connected directly to the output terminals (U,V, W) of the frequency inverter.
In case of overtemperature of the choke caused by too high switching frequencies and/or too long
cables, the inverter will trip with "external trip".
To prevent the cooling air of the frequency
inverter against pre-heating and to cool the
choke, it is recommended to place the choke
appr. 100...150 mm above the frequency
inverter.
