Category C2 – First environment - commercial use
Power Modules with additional line filter
● fulfill the requirements relating to cable-conducted noise interference emission
(interference), if
–
a shielded cable with low capacitance is used,
– the current does not exceed the rated input current (see Specific technical data
(Page 87)),
– the pulse frequency does not exceed 4 kHz, and
– the cable is not longer than 150 m.
● can cause high-frequency disturbances. In this case, damping measures may be required
in order that the requirements relating to radiated noise interference can be fulfilled.
Note
Devices for use in Category C2 – first environment, commercial use – must be installed by a
specialist with the appropriate experience for installing and/or commissioning power drive
systems, including their EMC aspects.
Category C2 – Second environment
Power Modules with additional line filter
● fulfill the requirements relating to cable-conducted noise interference emission
(interference), if
–
a shielded cable with low capacitance is used
– the current does not exceed the rated input current (see Specific technical data
(Page 87)),
– the pulse frequency does not exceed 4 kHz, and
– the cable is not longer than 150 m.
● can cause high-frequency disturbances. In this case, damping measures may be required
in order that the requirements relating to radiated noise interference can be fulfilled.
Category C3 – Second (industrial) environment
● Power Modules can be installed in Category C3 – second environment – and do not
require any authorization for connection.
● For motor cable lengths in the range >100 m to 150 m an additional basic interference
suppression module shall be provided on the line side (available on request).
