It is necessary that these instructions must be followed to conformed to EMC Directive.
Follow the usual safety procedures when working with electrical equipment. All electrical connec- tions to the filter, Drive and motor must be made by a qualified electrical technician.(Refer to Fig.
Use the correct filter according to Table
Install the Drive and filter in a electrically shielded metal cabinet.
The back panel of the wiring cabinet of board should be prepared for the mounting dimensions of the filter. Care should be taken to remove any paint etc. from the mounting holes and face area of the panel. This will ensure the best possible grounding of the filter.
Use a screened cable for the control , motor and other main wiring which are connected to the Drive. The screens should be securely grounded.
It is important that all wire lengths are kept as short as possible and that incoming mains and outgoing motor cables are kept well separated.
In case of a ferrite ring is provided with the filter, fit a ferrite ring to the motor cable with the 3 phase conductors only passing twice through the center of the ferrite.
