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.
