Cautions and warnings
Please read all warning and safety notes carefully before installing the filter and putting it into operation
(see ). The same applies to the warning signs on the filter. Please ensure that the signs
are not removed nor their legibility impaired by external influences.
Death, serious bodily injury and substantial material damage to equipment may occur if the appropriate
safety measures are not carried out or the warnings in the text are not observed.
Using according to the terms
The filters may be used only for their intended application within the specified values in lowvoltage
networks in compliance with the instructions given in the data sheets and the data book.
The conditions at the place of application must comply with all specifications for the filter used.
Warning
It shall be ensured that only qualified persons (electricity specialists) are engaged on work such
as planning, assembly, installation, operation, repair and maintenance. They must be provided
with the corresponding documentation.
Danger of electric shock. Filters contain components that store an electric charge. Dangerous
voltages can continue to exist at the filter terminals for longer than five minutes even after the
power has been switched off.
The protective earth connections shall be the first to be made when the filter is installed and the
last to be disconnected. Depending on the magnitude of the leakage currents, the particular
specifications for making the protective earth connection must be observed.
Impermissible overloading of the filter or filter, such as with circuits able to cause resonances,
impermissible voltages at higher frequencies etc. can lead to bodily injury and death as well as
cause substantial material damages (e.g. destruction of the filter housing).
Filters must be protected in the application against impermissible exceeding of the rated currents
by overcurrent protective devices.
In case of leakage currents >3.5 mA you shall mount the PE conductor stationary with the required
cross section before beginning of operation and save it against disconnecting. For leakage
currents IL
1) ≤10 mA the PE conductor must have a KU value2) of 4.53); for leakage currents
IL >10 mA the PE conductor must have a KU value of 64).
Output chokes and output filters must be protected in the application against impermissible exceeding
of the component temperature.
The converter output frequency must be within the specified range to avoid resonances and uncontrolled
warming of the output chokes and output filters.
Because the product can become very hot during operation, there is the risk of burns if
touched. The product can remain hot for some time after the power is switched off!
The table below summarizes the safety instructions that must be observed without fail. A detailed
description can be found in the relevant chapters of the databook.
Selecting a filter
When selecting a filter, it is mandatory to observe the rated data of the equipment (such as its rated input
current, rated voltage, harmonic content etc.) as well as the derating instructions
Selection guide for converter filters, Rated voltage
When power distribution systems deviating from the symmetric TN-S system is to check the suitability of the filters and the allowed voltages including the fault cases.
Power distribution systems,
Protection from residual voltages
Discharge resistors
Active parts must be discharged within 5 s to a voltage of less than 60 V (or 50 μ C). If this limit cannot be observed due to the operating mode, the hazardous point must be permanently marked in a clearly visible way.
Safety regulations,
Filters which are not permanently connected (e.g. when the test voltage is applied to the filter at the incoming goods inspection) must be discharged after the voltage has been switched off.
Safety regulations,
Installing and removing of filters, Installation
When installing and removing our filters, a voltage-free state must be set up and secured with observance of the five safety rules described in EN 50110-1.
Safety regulations,
Use in IT systems The special features of the IT system ("first fault case" and other fault cases) shall be observed.
Power distribution system (network types)
Safety notes on leakage currents
The filter leakage currents specified in the data book are intended for user information only.The maximum leakage current of the entire electrical equipment or appliance has to be limited for safety reasons. Please obtain the applicable limits for your application from the relevant regulations, provisions and standards.
Voltage derating
Hazards caused by overloading the filters
If the permissible limits for the higher-frequency voltages at the filter are exeeded, the filter may be damaged or destroyed.
Voltage derating,
Current derating at elevated ambient temperatures
Non-observance of the current derating may lead to overheating and consequently represents a fire hazard.

Please read Cautions and warnings
Important notes at the end of this document.
Protective earth connection at operating currents >250 A
For operating currents greater than 250 A, we recommend the PE connection to be set up between
the feed (filter: line) and output (filter: load) not via the PE terminal bolt in the filter housing.
Mounting instructions, Mounting position
Note the mounting position of the filters! It must always be ensured that natural convection is not impaired.
Mounting instructions, Long motor cables
Long motor cables cause parasitic currents in the installation. The cable lengths indicated for the output chokes and output filters serve for orientation. The user must check the technical parameters and especially the choke temperatures for the respective application.

Display of ordering codes for TDK Electronics products The ordering code for one and the same product can be represented differently in data sheets, data books, other publications, on the company website, or in order-related documents such as shipping notes, order confirmations and product labels. The varying representations of the ordering codes are due to different processes employed and do not affect the specifications of the respective products.
