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 in accordance with EN 61000-2-4, Class 3. Connection of the line filter
to other line systems may result in 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/NETZ L1, L2, L3.
• Connect the outgoing cable to the line reactor to LOAD/LAST L1', L2', L3'.
Fire due to inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent
fire and smoke. This can cause serious injury or even death. This can also result in
increased failures and shorter service lives for devices/systems.
• For this reason, maintain the 100 mm clearances above and below the line filter.
High leakage currents when the protective conductor in the line feeder cable is interrupted
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

conditions:
– It has been installed so that it is protected against 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
