Cautions and warnings
Please read all safety and warning notes carefully before installing the EMC 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 EMC 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. EMC 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 EMC 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 EMC 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).
EMC filters and filters must be protected in the application against impermissible exceeding of
the rated currents by overcurrent protective circuitry.
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 IL1) <10 mA the PE conductor must have a KU value2) of 4.5 A3); for leakage
currents IL ≥10 mA the PE conductor must have a KU value of 6.4)
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.
1) IL = leakage current let-go
2) The KU value (symbol KU) is a classification parameter of safety-referred failure types designed to ensure protection against hazardous
body currents and excessive heating.
3) A value of KU = 4.5 with respect to interruptions is attained with: a) a permanently connected protective earth circuit ≥2.5 mm2
connected via shroud connectors (IEC 603092) and b) a protective earth circuit.
4) KU = 6 with respect to interruptions is achieved for fixedconnection lines ≥10 mm2 where the type of connection and line layout
correspond to the requirements for PEN conductors as specified in relevant standards.

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.

Instructions
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 in Chapters 9 and 10.
Rated voltage
When power distribution systems deviating from the
Power distribution
symmetric TN-S system it is to check the suitability of systems,
the EMC filters and the allowed voltages including the 7
fault cases.
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.
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 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.

Display of ordering codes for EPCOS products
The ordering code for one and the same product can be represented differently in data sheets,
data books, other publications and the website of EPCOS, 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. Detailed information can be found on the Internet under

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application.
As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar
with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or
failure before the end of their usual service life cannot be completely ruled out in the
current state of the art, even if they are operated as specified. In customer applications
requiring a very high level of operational safety and especially in customer applications in
which the malfunction or failure of an electronic component could endanger human life or
health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by
means of suitable design of the customer application or other action taken by the customer
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by
third parties in the event of malfunction or failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as hazardous). Useful information on this will be found in our Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order. We also
reserve the right to discontinue production and delivery of products. Consequently, we
cannot guarantee that all products named in this publication will always be available. The
aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of the "General Terms of Delivery for Products and Services in the Electrical Industry" published by the German Electrical and Electronics Industry Association
(ZVEI).
