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
NOTICE
Damage to additional loads as a result of undesirable line harmonics
Line harmonics can occur if line filters that differ from those listed in this Manual are used.
These can disturb or damage other loads connected to the line supply.
• Only use line filters that are listed in this Manual.

WARNING
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
