3.6.1 Mains choke
A mains choke is an inductor which can be connected into the mains cable of the frequency inverter.
Mains chokes can be used together with RFI filter and / or motor filters.
The mains choke has the following functions:
z Reducing system perturbations
– The curved shape of the mains current is approached to the sinusoidal shape.
z Reducing the mains current
– Reducing the effective mains current (i.e. reducing the mains, cable, and fuse load).
z Improving the service life of the 8200 vector
– Reducing the AC current load on the electrolytic capacitors in the DC bus serves to prolong
their service life.

 Note!
z Some 8200 vector frequency inverters must always be operated with a mains
choke, independent of EMC measures.
z When operating with a mains choke the maximum motor voltage does not reach
the value of the mains voltage - typical voltage drop at rated frequency and rated
device current: 6 %.
3.6.1.1 Basic rules for wiring
z Themainschokeiswiredviasinglecorestothemains.
z The cable cross-section must be rated for the assigned fuse protection (EN 50178).
