2.1 TTComponentsTT
SIDAC line reactors/commutating reactors
SIDAC line reactors and commutating reactors have the following properties:
SIDAC line reactors/commutating reactors are installed upstream of the 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 DC drive or three-phase AC
drive.
SIDAC RFI suppression filters damp and limit conducted high-frequency (> 150 kHz to 30
MHz) interference voltages.
RFI suppression filters avoid mutual interference caused by high-frequency interference
currents.
SIDAC output reactors and sine-wave filters
SIDAC output reactors and sine-wave filters have the following properties:
SIDAC output reactors and SIDAC sine-wave filters are installed downstream of the
three-phase AC drive (frequency converter).
SIDAC output reactors and SIDAC sine-wave filters increase the service life of the motor
and improve system reliability.
SIDAC smoothing reactors
SIDAC smoothing reactors have the following properties:
SIDAC smoothing reactors are used in the load circuit of DC drives.
SIDAC smoothing reactors reduce the harmonic content for the DC motor as well as the
rate of current rise, thereby enabling use of DC high-speed circuit breakers.

2.2 TTDevice descriptionTT
2.2 TDevice descriptionT
Device versions
The output filters are offered in three-phase design in degree of protection IP00. All sine-
wave filters are equipped with safe-to-touch terminals, for the output reactors the 4EP types
are equipped with safe-to-touch terminals, and the 4EU types are equipped with flange
connections.
Application
Sine-wave filters and output reactors are used on the load side of frequency converters and
the motor currents flow through these components. They enable use of shielded motor
cables 200 m in length and non-shielded motor cables that are 300 meters in length.
Sine-wave filters filter the frequency converter output variables and thus simulate line-like
conditions for the motor. They ensure that the motor is supplied with nearly sinussoidal
currents and voltages. This reduces motor losses and magnetic motor noise levels.
Output reactors compensate capacitative switching currents and limit the voltage rate of rise
on the motor terminals.
See section 8.1 Operation, for general use conditions.
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.
Discharging the capacitors (for sine-wave filters)
Ensure that the energy stored in the capacitors of the sine-wave filters can be quickly
reduced, so that the voltage at the terminals drops to within permissible levels.
WARNING
It must be verified that the disconnected sine-wave filter is free of voltage!

3.1 TFunctional optimizationT
Through the combination of reactor and filter components around the converter, abatement
of harmonics can be improved.
SIDAC RFI suppression filters
SIDAC RFI suppression filters have the following properties:
SIDAC RFI suppression filters are installed upstream of the DC drive or three-phase AC
drive. They dampen and limit the conducted, high frequency (> 150 kHz to 30 MHz)
interference voltages.
RFI suppression filters avoid mutual interference caused by high-frequency interference
currents.
Under some conditions, use of a sine-wave filter increases the maximum permissible
motor cable length, which can be limited by the use of the RFI suppression filter.
Line reactors
To benefit from an additional reduction in phase effects on the system, combine an RFI
suppression filter with a SIDAC line reactor/commutating reactor.
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.

4.1 TMethod of operationT
Output reactor functions
The output reactors function in the following manner:
Output reactors are used on the load side of frequency converters. They compensate
capacitative switching currents and limit the voltage rate of rise on the motor terminals if long
motor cables are used.
This means that longer motor cables can be used. The converters can be better utilized as
the load with harmonic currents is reduced.
Sine-wave filter functions
Sine-wave filters function in the following manner:
Sine-wave filters are used on the load side of frequency converters. Sine-wave filters filter
the frequency converter output variables and thus simulate line-like conditions for the motor.
In addition to limiting the voltage rate of rise at the motor terminals in accordance with DIN
VDE 0530 or EC 60 034-17, the possibility of longer motor cables is provided. The
generation of noise on the motor is significantly reduced. The service life of the motor is
extended by the reduced applied voltage to the insulating system.

5.2 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 particularly 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.

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 separating plates between power cables and signal cables.
Ensure multiple grounding of separating plates.
Rule 3
Connect contactors, relays, solenoid valves, electromechanical operating 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.

5.2 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 capacitances and coupling inductances 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 coupling. 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!).
Ensure that there is a separate power supply for each converter.
Rule 13
Avoid interference coupling 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 bare, 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
separating plates. Suitable motor cables are, for example, Siemens PROTOFLEX-EMV-
CY (4 x 1.5 mm² to 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 stranded wire. The
motor terminal box must not be made of plastic.

2 Metric/heavy-gauge threaded joint
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
separating plates.
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, sinusoidal 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 separating plates 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

Installation
Install the sine-wave filter or the output reactor on a bare metal plate.
Mount the sine-wave filter or the output reactor in a cabinet as follows:
Install the sine-wave filter or the output reactor as close to the converter as possible.
When laying cables, keep them as short as possible.
Lay out the motor cables separate from the other cables, such as power supply cable so
that interference cannot be coupled.
The output reactor / sine-wave filter are each fastened with 4 screws via the fastening
bores provided in the base plate. The bore dimensions and the strength class of the
screws used are specified in the following dimension drawings.
Mounting position
The mounting position of the sine-wave filter or the output reactor must be selected in such a
manner that the cooling channels - if present - are arranged vertically.
In addition, ensure that the cooling air flow (natural convection) is not impacted by
neighboring components, connecting lines, etc. The capacitors of the sine-wave filter should
not be impacted by the waste heat of the reactor.

EMC-compliant configuration
To ensure trouble-free operation of the sine-wave filter / output reactor, the configuration
of the drive system must be EMC-compliant. The basic rules for the EMC-compliant
configuration of drive systems are outlined in section 5.
Install the converter and the sine-wave filter / output reactor on a common 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
sine-wave filter / output reactor are paint-free to ensure electrical contact with the
mounting plate.
If the motor is connected via a shielded cable, place the shield on the motor and on the
sine-wave filter / output reactor so that it is surface connected.
