NOTICE
Line filter damage by connecting to impermissible line supply
The line filters are only suitable for direct connection to line supplies with grounded neutral
point. Connecting the line filter to another line supply will damage the line filter.
• Only connect the line filter to a line supply with grounded neutral point.
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 supply cable to LINE L1, L2, L3.
• Connect the outgoing line to line reactor at LOAD L1´, L2´, L3´ (U, V, W).
NOTICE
Damage caused by using third party filters
According to product standard IEC 61800-3, radio interference suppression corresponding to
the application conditions is required, and is legally stipulated in the EU (EMC Directive). Line
filters and line reactors are required in order to comply with this standard. The use of filters of
other makes can lead to limit value violations, resonances, overvoltage, and irreparable
damage to motors or other equipment.
• The machine manufacturer must provide verification that the machine equipped with the
NOTICE
Destruction or damage of components by incorrectly connecting the line filter
When incorrectly connecting the line filter, components can be destroyed or damaged.
• Connect the line filter in accordance with the instructions in the technical documentation.
• Do not connect any additional loads downstream of the line filter.
NOTICE
Damage caused by connecting several loads to the same line infeed point
Damage can be caused if several loads are connected to the same line infeed point.
• Provide interference suppression for the other loads using appropriate line filters. To prevent

Disconnect the line filter for a high-voltage test
If a high-voltage test is conducted in the system with an alternating voltage, you must
disconnect the line filters in order to obtain a correct measurement result.

mutual interference, it is not permissible that this line filter is equipped with capacitors on
the line side with respect to ground. A filter from the B84144A*R120 (EPCOS) series is
recommended.
