Overview
Internal EMC filter
Variants with internal EMC filter for both Class A and Class B
environments are available.
• Class A
• Class B
An inverter with an internal filter can be used with a 30 mA resid-
ual-current circuit-breaker, and is only suitable for hardwired in-
stallations.
A non-filtered inverter together with the optional "Class B with
low leakage currents filter" has a leakage current of < 3.5 mA
(shielded motor cable up to 5 m).
Supplementary Class B EMC filter
Available for inverters with an internal Class A EMC filter.
With this filter, the inverter complies with the emission standard
EN 55 011, Class B.
The requirements are fulfilled using shielded cables with a max.
length of 25 m.
Class B filter with low leakage currents
With this filter, the unfiltered inverter complies with the emission
standard EN 55 011, Class B. The leakage currents are reduced
to < 3.5 mA.
Unfiltered inverters can be used for power drive systems in
category C1 installations (general availability).
The requirements are fulfilled with
• shielded cables with a max. length of 5 m
• installation of the inverter in a metal enclosure (e.g. control
• 16 kHz pulse frequency (frame size B and C only)
For category C1 installations, a 16 kHz pulse frequency is gen-
erally recommended for ultrasonic operation and low motor
noise.
For Class A the requirements are fulfilled using shielded cables
with a maximum length of 10 m (for FS A) or 25 m (for FS B and
FS C). The limits comply with EN 55 011 Class A.
For Class B the requirements are fulfilled using shielded cables
with a maximum length of 5 m. The limits comply with
EN 55 011 Class B.

Line reactor
Line reactors are used to smooth voltage peaks or to bridge
commutating dips.
In addition, line reactors reduce the effects of harmonics on the
inverter and the power supply.
If the ratio of inverter rated power to mains short-circuit power is
less than 1%, a line reactor must be used in order to reduce the
current peaks.
According to EN 61 000-3-2 "Limits for harmonic currents with
device input current ≤16 A per phase", there are special consid-
erations for drives with 120 W to 550 W and 230 V single-phase
supplies which are used in non-industrial applications (1st envi-
ronment).
For devices with 120 W to 370 W, users must either fit the recom-
mended line reactors or apply to the power utility company for
authorization to connect the devices to the public power supply.
No limits are currently defined in the EN 61 000-3-2 standard for
professionally used devices with a connected load >1 kW. This
means that inverters with an output power ≥ 0.75 kW comply
with the EN 61 000-3-2 standard.
