Selecting a filter
When selecting a filter, it is mandatory to observe the Selection guide for
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

symmetric TN-S system it is to check the suitability of systems,
the EMC filters and the allowed voltages including the
fault cases.

Protection from
residual voltages
Discharge resistors
Active parts must be discharged within 5 s to a Safety regulations,
voltage of less than 60 V (or 50 µ C). If this limit 6.1
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 Leakage current,
are intended for user information only.The maximum 8.4
leakage current of the entire electrical equipment or Leakage current,
appliance has to be limited for safety reasons. Please 8.6
obtain the applicable limits for your application from
the relevant regulations, provisions and standards.
Voltage derating
If the permissible limits for the higher-frequency Voltage derating,
voltages at the filter are exceeded, the filter may be 9.8
damaged or destroyed.
Hazards caused by
overloading the filters
Current derating at
elevated ambient
temperatures
Non-observance of the current derating may lead to Current derating,
overheating and consequently represents
hazard.
