Integrated EMC filter

Versions with integrated EMC filters class A and class B are available for the corresponding environments.

• Class A
  The requirements are fulfilled when shielded cables with a max. length of 10 m (32.8 ft) (for frame size FSA) or 25 m (82 ft) (for frame sizes FSB and FSC) are used. The limits comply with EN 55011 class A for conducted interference.
• Class B
  The requirements are fulfilled when shielded cables with a max. length of 5 m (16.4 ft) are used. The limits comply with EN 55011 class B for conducted interference.

An inverter with an integrated EMC filter can be used with a 30 mA residual-current circuit breaker and is only suitable for installations with fixed wiring.

Inverters without filters, which are used with "EMC filter classВ B with low leakage currents", have a leakage current < 3.5В mA (up to 5В m (16.4 ft) shielded motor cable).

Additional EMC filter classВ B

Available for inverters with an integrated EMC filter.

With this filter, the inverter complies with the emission standard EN 55011, class B for conducted interference.

The requirements are fulfilled using shielded cables with a max. length of 25 m (82 ft).

EMC filter, class B with low leakage currents

With this filter, the unfiltered inverter complies with the emission standard EN 55011, class B for conducted interference. The leakage currents are reduced to <В 3.5В mA.

Unfiltered inverters can, therefore, be used for drive systems in Category C1 installations.

The requirements are fulfilled with

• Shielded cables with a max. length of 5 m (16.4 ft)
• Installation of the inverter in a metal housing (e.g. control cabinet)
• Pulse frequency of 16 kHz (only for frame sizes FSB and FSC)

With Category C1 installations, generally a pulse frequency of 16 kHz is recommended for inverter operation in the inaudible spectrum and for quiet motor operation.

Line reactor

Line reactors are used to smooth voltage peaks or to bridge commutating dips.

Line reactors also reduce the effects of harmonics on the inverter and the power supply.

If the ratio of the rated inverter power to supply short-circuit power is less than 1 %, a line reactor must be used in order to reduce the current peaks.

In accordance with the specifications of EN 61000-3-2 "Limits for harmonic currents with device input current ≤ 16 A per phase", there are special aspects for drives with 120 W to 550 W and 230 V single-phase supplies which can be used in non-industrial applications (environment 1).

For devices with 120 W to 370В W, either the recommended line reactors must be installed or permission obtained from the power utility company for the connection to the public supply system.

In accordance with the specifications of EN 61000‑3‑12 "Limits for harmonic currents > 16 A and ≤ 75 A per phase", permission must be obtained from the power utility company to operate drives connected to the public low-voltage line supply. For the harmonic currents, see the Operating Instructions.

Selection and ordering data

The line-side power components listed here must be selected in accordance with the inverter. EMC filters and line reactors cannot be installed as base components.

The inverter and associated line-side power components have the same rated voltage.

All line-side power components are certified to UL (with the exception of fuses). 3NA3 fuses and 3RV circuit breakers are recommended for European countries.

Fuses for use in North America must be UL-certified Class H, J or K fuses with a rated voltage of 250В VВ AC.

Short Circuit Current Rating (SCCR)
according to UL

Applies to industrial control panel installations to NEC Article 409 or UL 508A.

• SINAMICSВ G110: 10В kA (up to maximum 100В kA)

Additional information about the listed fuses and circuit breakers can be found in Catalogs LVВ 10, ICВ 10 and ICВ 10В AO.
