Safety instructions for line filters

Electric shock in the event of missing touch protection
Touching live components can result in death or serious injury.
• For the line filter, use touch protection according to IPXXA or corresponding to the local
Electric shock caused by high leakage currents when the protective conductor in the line
feeder cable is interrupted
Drive components conduct high discharge currents via the protective conductor. Touching
conductive parts when the protective conductor is interrupted can result in death or serious
injury.
• Ensure that for increased leakage currents, the local regulations for protective
• Within a machine/system, ensure that the protective conductor fulfills at least one of the
Fire through overheating due to insufficient ventilation clearances
Insufficient ventilation clearances result in overheating with danger to persons as a result of
smoke and fire. Further, the line filter can be thermally damaged.
• Ensure 100-mm ventilation clearances above and below the line filter.

WARNING
installation regulations.
WARNING
conductors at the installation site are complied with.
following conditions:
For fixed connection:
– The protective conductor is routed so that it is protected against mechanical damage
along its complete length.
– As a conductor of a multi-conductor cable, the protective conductor has a cross-
section ≥ 2.5 mm² Cu.
– For an individual conductor, the protective conductor has a cross-section ≥ 10 mm²
Cu.
– The protective conductor consists of two conductors with the same cross-section.
When establishing the connection using an industrial plug connector according to EN
60309:
– As a conductor of a multi-conductor cable, the protective conductor has a cross-
section ≥ 2.5 mm² Cu.
Cables routed within control cabinets or closed machine housings are considered to
