3.2 Power connections
There are two options for radio interference suppression of the 8200 vector frequency inverter:
8200 vector frequency inverter with integrated RFI filter (types E82xVxxxKxC0xx)
Compliance with the limit classes A and B according to EN 55011 without additional
measures.
The permissible motor cable length depends on the limit class to be observed, which 8200
vector type is used, and the switching frequency (type-specific data on demand).
8200 vector frequency inverter without integrated RFI filter (types E82xVxxxKxC2xx)
Compliance with the limit classes A and B according to EN 55011 with footprint RFI filter for
long motor cables. The RFI filters are designed so that they can be mounted directly below
the 8200 vector frequency inverter. The footprint RFI filters also enable the frequency inverters
to be mounted side by side.
You can choose from two different filter types:
For motor cables up to 20 m: RFI filter SD (Short Distance).
– RFI filters SD are additionally specified for being operated on a 30 mA earth-leakage circuit
breaker.
For motor cables from 20 m to 50 m: RFI filter LD (Long Distance).
For motor cables from 50 m to 100 m the RFI filter LD is combined with a motor filter.
Limitation of harmonic currents
The European Standard EN 61000-3-2 determines limit values for limiting harmonic currents in the
supply system. Non-linear loads (e.g. frequency inverters) produce harmonic currents which may
have an influence on the supply system and thus interfere with other loads. The Standard wants to
secure the quality of the public supply system and reduce the mains load.
Note: The Standard only applies to public mains and electrical equipment < 1 kW power or
electrical equipment with a mains current of up to max. 16 A:
Mains systems which have their own transformer station as common in industry are not public. The
Standard does not apply to them.
If the electrical equipment consists of several components (e.g. 8200 vector), the total unit must
comply with the limit values defined in the Standard. Further information is given in the chapters
3.2.1.2 and 3.2.2.2.
