for converters and power electronics

Caution and warnings

S Please note the advices in our data book “EMC Filters” (latest edition); attention should

be paid to the chapter “General safety notes”.

S 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.

S 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 min-

utes even after the power has been switched off.

S 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 cur-

rents, the particular specifications for making the protective−earth connection must be ob-

served.

S Impermissible overloading of the EMC filter, such as with circuits able to cause reso-

nances, 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 hous-

ing).

S EMC filters must be protected in the application against impermissible exceeding of the

rated currents by overcurrent protective.

S 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 disconnect-

3) 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.

A value of KU = 4.5 with respect to interruptions is attained:

spond to the requirements for PEN conductors as specified in relevant standards.
