This equipment is used in industrial high-voltage installations. During operation, this
equipment contains live, bare parts. For this reason, they could cause severe injury or
significant material damage if the required covers are removed, if they are used or operated
incorrectly, or have not been properly maintained.
When the machines are used in non-industrial areas, the installation location must be
protected against unauthorized access (protective fencing, appropriate signs).
Preconditions
The persons responsible for the safety of the plant or system must ensure that the following
conditions are met:
●Basic planning work for the system and all work relating to transportation, assembly,
installation, commissioning, maintenance and repairs is carried out by qualified personnel
and checked by responsible, suitably skilled personnel.
●The Operating Instructions and machine documentation are always available.
●The technical specifications regarding the applicable installation, connection,
environmental, and operating conditions are always observed.
●The plant-specific assembly and safety guidelines are observed and personal protection
equipment is used.
●Unqualified personnel are forbidden from using these machines and working near them.
These Operating Instructions are intended for qualified personnel and only contain
information and notes relating to the intended purpose of the machines.
The Operating Instructions and machine documentation are written in different languages as
specified in the delivery contracts.
Note
Support by SIEMENS service centers
We recommend engaging the support and services of your local Siemens service center for
all planning, installation, commissioning and maintenance work.

Components that can be destroyed by electrostatic discharge (ESD)
CAUTION
Components sensitive to electrostatic charge
The board contains components that can be destroyed by electrostatic discharge. These
components can be easily destroyed if not handled properly. If you do have to use
electronic boards, however, please observe the following:
•You should only touch electronic boards if absolutely necessary.
•When you touch boards, however, your body must be electrically discharged
beforehand.
•Boards must not come into contact with highly insulating materials (such as plastic
parts, insulated desktops, articles of clothing manufactured from man-made fibers).
•Boards must only be placed on conductive surfaces.
•Boards and components should only be stored and transported in conductive packaging
(such as metalized plastic boxes or metal containers).
•If the packaging material is not conductive, the boards must be wrapped with a
conductive packaging material (such as conductive foam rubber or household aluminum
foil).

Description
The du/dt filter plus voltage peak limiter comprises two components: the du/dt reactor and
the Voltage Peak Limiter, which cuts off the voltage peaks and returns the energy to the DC
link.
The du/dt filters plus Voltage Peak Limiter must be used for motors for which the proof
voltage of the insulation system is unknown or insufficient.
du/dt filters plus Voltage Peak Limiters limit the rate of voltage rise to values < 500 V/µs and
the typical voltage peaks with rated line voltages to < 1000 V at Uline < 575 V

NOTICE
Do not interchange the I/Os
The terminals on the voltage limiting network (Voltage Peak Limiter) must always be
connected as follows:
•Cable from the DC link of the Power Module at DCP, DCN and
•Cable to the du/dt reactor 1U2, 1V2, 1W2.
Failure to connect the terminals correctly could damage the voltage peak limiter.

NOTICE
Use only approved du/dt filters
If du/dt filters plus Voltage Peak Limiters are used that SIEMENS has not approved for
SINAMICS, these du/dt filters may be damaged.
CAUTION
Hot surfaces
The surface temperature of the du/dt reactors may exceed 80 °C.
WARNING
Risk of destruction during operation with increased pulse frequency
When a du/dt filter plus Voltage Peak Limiter is used with SINAMICS G120, the pulse
frequency of the Power Module must not exceed 2.5 kHz/4 kHz. Setting a higher pulse
frequency can lead to destruction of the du/dt filter.
NOTICE
No operation without connected motor
When a du/dt filter plus Voltage Peak Limiter is used, the drive must not be operated
without a connected motor, otherwise the filter can be destroyed.
NOTICE
Activation during commissioning
If a du/dt filter plus Voltage Peak Limiter is connected to the Power Module, it is essential
that it is activated during commissioning (p0230 = 2).
NOTICE
Component cooling
Provisions for component cooling must be made at the installation site. Power loss data is
given in the technical specifications.
Note
Setting range for pulse frequencies
It is permissible to set pulse frequencies in the range between the rated pulse frequency and
the relevant maximum pulse frequency when a du/dt filter plus Voltage Peak Limiter is used.
When so doing,
take into account the "Current derating as a function of the pulse frequency;
see Technical data.

Limiting the rate of voltage rise and the voltage peaks using an output reactor and du/dt filter plus
Voltage Peak Limiter
Fast-switching IGBTs in the converter result in high voltage gradients du/dt at the converter
output. If long motor cables are used, this leads to an additional current load on the
converter due to capacitive charge/discharge currents. The high voltage gradients, and the
resulting transients at the motor terminals, cause the motors' electrical winding load to
increase as compared with direct on-line operation.
The du/dt filter plus Voltage Peak Limiter limits the rate of voltage rise to values < 500 V/µs
and the typical voltage peaks ÛLL to < 1000 V at Uline ≤ 575 V (for motor cable lengths of ≤
150 m)

Important safety precautions
WARNING
Dangerous electrical voltage
The devices are operated with high voltages.
All connection work must be carried out in a no-voltage condition!
All work on the device must be carried out by trained personnel only.
Death, serious injury, or substantial material damage can result if these warning notices are
not observed.
Work on an open device must be carried out with extreme caution because external supply
voltages may be present. The power and control terminals may be live even when the
motor is not running.
Dangerously high voltage levels are still present in the cabinet up to 5 minutes after it has
been disconnected due to the DC link capacitors on the Power Module. For this reason, the
unit should not be opened until a reasonable period of time has elapsed.
The operator is responsible for ensuring that the du/dt filter with Voltage Peak Limiter and
other components are installed and connected in accordance with the recognized technical
rules in the country of installation and applicable regional guidelines. Special attention
should be paid to cable dimensioning, fuses, grounding, shutdown, disconnection, and
overcurrent protection.
If a protective device trips in a branch circuit, a fault current may have been interrupted. To
reduce the risk of fire or an electric shock, the current-conducting parts and other
components in the cabinet unit should be inspected and damaged parts replaced. When a
protective device trips, the cause of the trip must be identified and rectified.

Connection
When connecting the du/dt reactor and Voltage Peak Limiter, you must take into account the
following conditions to ensure that it functions correctly:
●Control cables must be routed separately from power cables. Power cables are the motor
cable or the connecting cables from the DC link of the Power Module (terminals
DCP/DCN) to the Voltage Peak Limiter. In particular, you must ensure that control cables
and power cables are not routed in parallel in a joint cable raceway, even if all the cables
are shielded.
●It is recommended to use shielded motor cables. If a shielded motor cable is used, its
shield should be connected through a large surface area with the shield connection plate
in the cabinet and at the motor housing.
●The ground wire for the motor must be fed directly back to the Power Module.

WARNING
Risk of fire and damage to equipment due to short-circuit/ground fault
The cables to the DC link of the Power Modules must be routed so that a ground fault or
short circuit can be ruled out. A ground fault can result in fire with the associated smoke.
•Protect the cables from mechanical damage.
•Comply with local installation regulations that enable this fault to be ruled out.
In addition, apply one of the following measures:
•Use cables with double insulation.
•Maintain adequate clearance, using spacers, for example.
•Route the cables in separate cable ducts or pipes.
