NOTICE
Line lter damage by connecting to impermissible line supply
The line lters are only suitable for direct connection to line supplies with grounded neutral
point. Connecting the line lter to another line supply will damage the line lter.
• Only connect the line lter to a line supply with grounded neutral point.
NOTICE
Line lter damage due to interchanged connections
The line lter 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 lters
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
lters and line reactors are required in order to comply with this standard. The use of lters of
other makes can lead to limit value violations, resonances, overvoltage, and irreparable
damage to motors or other equipment.
• The machine manufacturer must provide verication that the machine equipped with the
drive products and the installed suppression elements, e.g. line lters, is EMC-compliant
before the machines are placed in the market.
NOTICE
Destruction or damage of components by incorrectly connecting the line lter
When incorrectly connecting the line lter, components can be destroyed or damaged.
• Connect the line lter in accordance with the instructions in the technical documentation.
• Do not connect any additional loads downstream of the line lter.
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 lters. To prevent
mutual interference, it is not permissible that this line lter is equipped with capacitors on
the line side with respect to ground. A lter from the B84144A*R120(EPCOS) series is
recommended.
Note
Disconnect the line lter for a high-voltage test
If a high-voltage test is conducted in the system with an alternating voltage, you must
disconnect the line lters in order to obtain a correct measurement result.
