Emc (Electro-Magnetic Compatibility) - BMR SFU-0302-SSE Manual

SFU-0302 SSE
12. EMC
This device was developed for use in industrial environments. For trouble-free operation and to
reduce emitted interference, the following should be observed during wiring of the equipment:
•
The EMC of a machine or device is affected by all connected components (motor spindle, length
and type of cables, wiring, etc..). Under certain conditions the use of additional filters can be
necessary to maintain the current laws.
•
The earth and shield connections of all those devices used in conjunction with the frequency
converter should be as short as possible and have as large a cross-section as possible.
•
Control devices used with the frequency converter (PLC, CNC, IPC, ...) should be connected to a
common earth/earth terminal bar.
•
For mechanical installation, use serrated lock washers to guarantee good electrical contact with
the housing.
•
All connections both to and from the frequency converter should be via shielded cable.
•
The shield must be completely connected to PE (protective earth).
•
Supply cables, motor cables and control cables must be completely isolated from each other.
Where crossing cannot be avoided, cables should be laid at 90° to each other.
•
The control cable should be laid as far away as possible from the load cable.
