● SIDAC line reactors/commutating reactors are installed upstream of the three-phase DC
drive or three-phase AC drive.
● Line reactors/commutating reactors reduce the proportion of low-frequency harmonics on
the line, thereby improving the power factor.
● Line reactors/commutating reactors avoid mutual interference caused by low-frequency
noise and protect the converter input. The capacitive DC link of frequency converters is
protected.
SIDAC RFI suppression filters
SIDAC RFI suppression filters have the following properties:
● SIDAC RFI suppression filters are installed upstream of the three-phase DC drive or
three-phase AC drive.
● RFI suppression filters avoid mutual interference caused by high-frequency interference
currents.

2.2 TTDevice descriptionTT
2.2 TDevice descriptionT
Device versions
RFI suppression filters are available in single-phase and three-phase versions. Each device
is assigned to a converter requiring radio-interference suppression in respect of the line.
Most devices are equipped with finger-safe terminals and these filters offer IP20 degree of
protection. All filters with flat connectors are designed for IP00 degree of protection.
Application
RFI suppression filters are installed in the line-side supply, upstream of a converter. AC
currents with the mains frequency as the fundamental frequency flow through them.
EMC regulations
Compliance with EMC regulations must be ensured in individual cases by means of an
application-specific measurement. The converter's rating data must be taken into account
when selecting a filter.
Capacitor discharge
The filters feature built-in discharge resistors so that the energy stored in the capacitors can
be quickly reduced, thereby ensuring that the voltage at the terminals drops to within
permissible levels.
However, before carrying out any work on the filter, check that it is safely isolated from the
supply.

TProduct combinationT
3.1 TFunctional optimizationT
You can make the most of RFI suppression filters by combining them with other products
from the same product line.
Line reactors
To benefit from an additional reduction in phase effects on the system, combine the RFI
suppression filter with a SIDAC line reactor/commutating reactor.
SIDAC output reactors/sine-wave filters
To ensure optimum operation of the RFI suppression filter, a motor-cable length of 50 m is
recommended as the absolute maximum. When using an RFI suppression filter, the
maximum possible motor-cable length can be increased by using SIDAC output reactors or
sine-wave filters.
Application-specific measurement is required
Ensure compliance with EMC regulations in individual cases by means of an application-
specific measurement. This measurement must be requested and ordered separately. The
converter's rating data must be taken into account when selecting a filter.

Functions
RFI suppression filters support the following functions:
● RFI suppression filters damp and limit conducted high-frequency
(>150 kHz ... 30 MHz) interference voltages.
● Line filters for compliance with EN 55011 Class A are designed to reduce converter
interference voltages to within the limit values for industrial supplies.
● Line filters for compliance with EN 55011 Class B are designed to reduce converter
interference voltages to within the limit values for public supplies.
– Radio interference level B can generally only be achieved through the additional use
of a line reactor.
– These filters also ensure compliance with Class A limit values.
● Ensure compliance with EMC regulations in individual cases by means of an application-
specific measurement.

5.4 TEMC-compliant configuration of drive systemsT
The basic rules of EMC
The following 20 rules must be adhered to for the configuration of EMC-compliant drive
systems. Rules 1 to 13 apply on a general level. Rules 14 to 20 are particular important for
limiting emitted interference.
General rules
Rule 1
● Ensure that all metal parts of the control cabinet are surface-connected with good
conductivity (not paint on paint). If necessary, use contact washers or serrated lock
washers.
● When connecting the control-cabinet door to the control cabinet, use bonding strips that
are as short as possible (also see Rule 20).
● Suitable line/commutating reactors are recommended as a means of counteracting low-
frequency phase effects on the system and protecting the converter. You must install
these between the line connection and the RFI suppression filter inside a metal cabinet.
Ensure that the control-cabinet configuration, system configuration and wiring are carried
out in compliance with the rules of EMC-compliant configuration.
● On the line side, route the grounding to the motor via the reactor, filter and converter.

Grounding systems/machines and grounding drives
● The grounding of systems/machines is a protective measure.
● In the case of drives, grounding affects emitted interference and interference immunity.
● System grounding can be carried out point-to-point or two-dimensionally.
● For drives, select two-dimensional grounding, i.e. all the parts of the system that need to
be grounded are connected two-dimensionally or as a mesh.
– The motor must be connected using a shielded cable.
– Unshielded motor cables must only be used in conjunction with a sine-wave filter.
– The shield must be applied to the surface of the motor and converter.

contact area

3 Cable propping bar
Rule 2
● When laying the signal cables and power cables, ensure that sufficient space is left
between them (minimum distance: 20 cm).
● Avoid data links
● Provide separators between electric power cables and signal cables.
● Ensure multiple grounding of separators
Rule 3
Connect contactors, relays, solenoid valves, electromechanical hours counters, etc., inside
control cabinet using interference suppression combination, e.g. RC elements, diodes,
varistors. Install the protective circuit directly on the relevant coil.

TTOperation planningTT
5.4 TTEMC-compliant configuration of drive systemsTT
Rule 4
Twist unshielded cables from the same electric circuit (go and return conductors) or ensure
that the surface area between the go and return conductors is as small as possible to avoid
unnecessary frame antennae.
Rule 5
Avoid unnecessarily long cables Thus coupling capacities and coupling inductivities are kept
small.
Rule 6
Ground spare cores at both ends. This achieves an additional shielding effect.
Rule 7
Lay cables close to grounded plates to reduce interference injection. You should not,
therefore, route wiring and spare cables randomly within the cabinet; instead, keep them
close to the cabinet enclosure/mounting plates.
Rule 8
Use a shielded cable to connect tachometers, encoders and resolvers. Connect the shield to
the tachometer, encoder or resolver and to the converter, ensuring maximum contact area.
The shield must not be broken at any point, e.g. by intermediate terminals.
Rule 9
● Ground the shields of digital signal cables on both sides (sender and receiver), ensuring
maximum contact area and good conductivity.
● In the event of poor equipotential bonding between the shield connections, run an
additional equalizing conductor with a cross-section of at least
10 mm² parallel to the shield for the purpose of reducing the shield current.
● Multiple grounding of the shields (= connection to cabinet enclosure) is possible. Multiple
grounding of the shields is even possible outside the control cabinet.
● Foil shields are at least 5 times less effective than braided shields.
Rule 10
● Ground the shields of analog signal cables with good equipotential bonding on both
sides. Good equipotential bonding is achieved if Rule 1 is followed.
● If low-frequency interference occurs on the analog lines, e.g.: Speed/measured value
fluctuations as a result of equalizing currents (hum) then connect the analog signal shield
to the signal sink on one side, e.g. analog input of the converter. Ground the other side of
the shield via a capacitor (e.g. 10 nF/100 V Type MKT). The use of the capacitor means
that the shield is connected for high frequencies on both sides.

Rule 12
● If converters are to be operated by means of an external 24 V power supply, this supply
must not be connected to a number of loads that have been installed separately inside
different control cabinets (hum loops!).
● Ensure that there is a separate power supply for each converter.
Rule 13
● Avoid interference injection via the line connection.
● Connect the converter and PLCs/control electronics to different line supplies.
● If only one common line supply is available, isolate the PLCs/control electronics from the
line supply by means of an isolating transformer.

Rules for limiting emitted interference
Rule 14
● An RFI suppression filter must be used to ensure compliance with limit class A or B (EN
55011) even in cases where sine-wave filters or dv/dt filters have been installed between
the motor and the converter.
● The issue of whether an additional filter is required for further loads depends on the
controller used and how the rest of the control cabinet is wired.
Rule 15
● Ensure that the RFI suppression filter is located in the vicinity of the source.
● Ensure that the filter is surface-connected to the control-cabinet enclosure, mounting
plate, etc. A bright, metallic mounting plate is preferable (e.g. stainless steel, galvanized
steel), since the entire contact surface establishes the electrical contact. If a painted
mounting plate is used, the screw positions for mounting the frequency converter and and
RFI suppression filter must be paint-free to ensure electrical contact with the mounting
plate.
● Physically separate the input and output cables of the RFI suppression filter.
Rule 16
● Use shielded cables to connect all variable-speed motors in order to limit emitted
interference.
● Connect both sides of the shields to the relevant enclosures in a manner that ensures low
inductance (short and maximum possible contact area).
● Shield the motor cables inside the control cabinet or shield them by means of grounded
separators. Suitable motor cables include, for example, Siemens PROTOFLEX-EMV-CY
(4 x 1.5 mm² ... 4 x 120 mm²) with Cu shield. Cables with steel shields are not suitable.
● Use a suitable screwed joint with shield contact on the motor for the shield connection.
Make sure that there is a low-impedance connection between the motor terminal box and
motor housing. If necessary, use an additional flexible grounding wire. The motor terminal
box must not be made of plastic.

5.4 TTEMC-compliant configuration of drive systemsTT
Rule 17
Install a line reactor between the RFI suppression filter and the line supply.
Rule 18
Physically separate the power supply cable and motor cables, e.g. by using grounded
separators.
Rule 19
The shield between the motor and converter must not be broken at any point as a result of
integrating components such as output reactors, sine-wave filters, dv/dt filters, fuses and
contactors. Assemble the components on a mounting plate, which will simultaneously serve
as the shield connection for the incoming and outgoing motor cables. It may be necessary to
use grounded separators for the purpose of shielding the components.
Rule 20
● To limit interference radiation (particularly in the case of limit class B), all cables
connected to the control cabinet from the outside must be shielded in addition to the
power supply cable.
● When mounting inside a cabinet, install the RFI suppression filter (and if necessary a
reactor) in the direct vicinity of the converter.
● When laying cables, keep them as short as possible.
● When connecting the power supply cable to the RFI suppression filter (or reactor), ensure
that it is kept separate from other cables so that no interference can be injected into the
interference-suppressed power supply cable that would partially cancel out the effects of
the RFI suppression filter.
● Connect the housing of the converter and RFI suppression filter with low resistance for
high-frequency interference currents. This can be achieved by placing the converter and
RFI suppression filter on the same mounting plate. Ensure that the converter and RFI
suppression filter are surface-connected to this mounting plate. The best solution here is
to use a bare metal mounting plate (e.g. made of stainless steel or galvanized sheet-
steel), since the total contact surface establishes the electrical contact. If a painted
mounting plate is used, the screw positions for the converter and RFI suppression filter
must be paint-free to ensure electrical contact with the mounting plate.

Assembly/Installation
Install the RFI suppression filter on a bare metal plate.
Proceed as follows to install the RFI suppression filter inside a control cabinet:
● Install the RFI suppression filter (and reactor, if required) directly upstream of or next to
the converter.
● When laying cables, keep them as short as possible.
When connecting the power supply cable to the RFI suppression filter (or reactor), ensure
that it is kept separate from other cables so that no interference can be injected into the
interference-suppressed power supply cable that would partially cancel out the effects of
the RFI suppression filter.

EMC-compliant configuration
To ensure problem-free operation of the filter, the configuration of the drive system must be
EMC-compliant. The basic rules for the EMC-compliant configuration of drive systems are
outlined in the previous section.
Mounting and interference suppression
RFI suppression filters feature a metallic housing. The 4 screws used for screw mounting
ensure:
● Mechanical fastening
● That the RFI suppression filter is shielded by means of a generous contact-area
connection to the reference ground.
High-frequency interference currents
The housing of the converter and RFI suppression filter must be connected with low
resistance for high-frequency interference currents. To achieve this, proceed as follows:
● Install the converter and RFI suppression filter on a single bare metal mounting plate
(stainless steel or galvanized sheet-steel). The total contact surface establishes the
electrical contact.
● If a painted mounting plate is used, ensure that the screw positions for the converter and
RFI suppression filter are paint-free so that electrical contact with the mounting plate can
be ensured.
Note
Shielded cable for motor connection
If an output filter is not used in conjunction with a frequency converter, the motor must be
connected by means of a shielded cable. Ensure that the shield makes full surface
contact with the motor and converter.

Use in TN systems
RFI suppression filters must only be used in TN systems (grounded neutral point).
Definition: TN system
TN systems have one point directly grounded. The exposed conductive parts of the electrical
installation are connected to this point by protective conductors.
There are 3 different subsystems:
● TN-S system
● TN-C system
● TN-C-S system

Operation
The following must be observed when operating the RFI suppression filter:
● Compliance with the rating data on the rating plate is necessary if proper use of the RFI
suppression filter is to be ensured.
● If you notice any deviations from normal operation (increased power consumption,
temperature or levels of vibration, unusual noises or odors, monitoring devices tripping,
etc.), the device is probably no longer functioning correctly.
In such an event, you must notify the responsible service personnel immediately to
prevent faults that could result in personal injury or material damage.
● If in doubt, shut down the equipment concerned immediately.
