Note! All internal components and component boards, with the exception of the gal­vanically separated input and output terminals are connected to high voltage when the
frequency converter is connected to the mains. It is extremely dangerous to touch
these live parts. Touch may cause severe injury or death

The I/O terminals are separated from the high potential of the mains, but the relay out­puts and other I/O terminals may carry high voltages even if the frequency converter is
not connected to the mains.

Do not perform any high pot tests (megger) on the Vacon_SIN_B filters

The Vacon_RFI_A0 filters are intended for use in earthed supplies only
For unearthed (IT) supplies, contact our representative or us.

1 General

Modern frequency converters do not sup­ply a smoothly changing AC voltage , but a
pulsed DC voltage to the motor. The
pulses have very steep flanks, the du/dt
may reach several kV/µs. These steep
pulses may be dangerous to the insulation
of the motor. The pulses may also cause
various disturbing currents in galvanically
connected cables as well as radiated in­terference. The radiated interference is
usually grounded by the metallic enclosure
of the converter and does not cause any
problems in the environment. The galvani­cally coupled interference may have to be

filtered in order to achieve EMC compli­ance. The converter may also have to be
protected against various overvoltages
occurring in the supply.

Both input and output filters are available
for the Vacon CX_ range of drives. These
filters help compliance with the EMC
regulations. On the input side RFI filters
and additional chokes can be mounted, on
the output side du/dt filters or sinus filters.
No other filters are necessary. The basic
connection is shown in Figure 1-1

2. Filter types

2.1 RFI-filters

The table below shows the filters used in
order to make the Vacon CX___N range of
frequency converters comply with
EN50082-2 for the industrial environment
and with EN61800-3 for the domestic and
industrial environment. The filters must be
correctly installed and grounded.

There are no standards at present for IT­supplies (floating supplies)

The Vacon CX__ frequency converters
comply with the immunity requirements of
EN50081 and EN 61800-3 as standard.

Note that the filters 16 – 100 RFI5C2 are
designed to fit mechanically directly to the
corresponding drive. All other s are lo os e
and must be connected to the drive sepa­rately.

2.2 dU/dt filters

2.2.1 dU/dt – maker Platthaus

The Vacon CX- ranges use IGBT transis­tors as the output element. These semi­conductors give the correct voltage to the
motor, switching it at a very high speed, 2

- 4 kV/µs. This high speed will, under cer­tain circumstances, cause extra voltage
stress on the main insulation of the motor.

Usually there are no problems with motors
designed for a 400 V supply. Such motors
are usually designed for a voltage level of
1200 V, which exceeds the frequency
converter induced stress.

In 500 V supplies the motor has to with­stand at least 1600 V. A dU/dt filter is often
required with these motors in order not to
exceed the allowable voltage stress.

In 690 V supplies the motor has to stand

at least 1800 V. A dU/dt filter is required in
these cases.

! In uncertain cases, confirm the rating
of the motor in frequency converter ap­plication with the motor manufacturer.

The dU/dt filter also reduces ground cur­rents, easing the job of earth-fault protec­tors. They also lessen the impact of the
various sources of bearing current.
All filters are IP00

The filters are LC filters, with a cut-off fre­quency of about 500 kHz. The exact value
changes due to component tolerances and
available standard values.

NOTE! Set the switching frequency pa­rameter to correspond the value printed
on nameplate of the filter.

2.2.2 dU/dt filter with resistance

The SH filter differs from the standard in that they contain a resistance to reduce the ‘ringing’
created by the interaction of the choke and the stray inductance of the motor. Functionally
they are equivalent.

2.3 Sine-filters

If you wish to avoid all extra voltage
stresses on the motor at all voltages, sine­filters can be used. They remove all high
frequency components from the motor
voltage. The voltage stresses on the motor

correspond to those existing in normal
DOL use on a source of the same voltage.

Note! Check that the set switching fre­quency corresponds the value printed
on nameplate of the filter.
