General
NOTICE
Line filter damage by connecting to impermissible line supplies
The line filters are only suitable for direct connection to TN or TT systems with grounded
neutral point. Line filters are designed for connection to systems with a continuous level to
voltage harmonics according to EN 61000-2-4, class 3. Connecting the line filter to other
systems causes damage.
• Only connect the line filter to TN or TT systems with grounded neutral point and a
NOTICE
Line filter damage due to interchanged connections
The line filter will be damaged if the input and output connections are interchanged.
• Connect the incoming line cable to LINE L1, L2, L3.
• Connect the outgoing cable to the line reactor to LOAD L1', L2', L3'.
Fire hazard due to overheating because of inadequate ventilation clearances
Insufficient ventilation clearances result in overheating with danger to persons as a result of
smoke and fire. Damage can still occur on the line filter.
• For this reason, maintain the 100 mm clearances above and below the line filter.
Danger to life due to high leakage currents caused by an interrupted external protective
conductor
The drive components conduct a high leakage current via the protective conductor.
Touching conductive parts when the protective conductor is interrupted can result in death
or serious injury.
• Ensure that the external protective conductor satisfies at least one of the following
14
continuous level to voltage harmonics in accordance with EN 61000-2-4, Class 3.

conditions:
– It has been laid so that it is protected from mechanical damage.
– For an individual core, it has a cross-section of at least 10 mm² Cu.
– If it is a conductor of a multi-conductor cable, it has a cross-section of at least 2.5
mm² Cu.
– It has a second protective conductor in parallel with the same cross-section.
– It complies with the local regulations for equipment with increased leakage current.
Cables laid within control cabinets or closed machine housings are considered to be
