RFI FILTERS
THE USE OF EMI/RFI FILTERS HELPS TO ENSURE TROUBLE FREE OPERATION ALONGSIDE
SENSITIVE DEVICES AND COMPLIANCE TO CONDUCTED EMISSION AND IMMUNITY STANDARS
EN 50081 -> EN61000-6-3:02 and EN61000-6-1:02.

INFORMATION.
NOTE
IN THE CASE WHERE A LEAKAGE CURRENT PROTECTIVE DEVICE IS USED ON THE INCOMING
POWER SUPPLY, IT MAY TRIP AT POWER-ON OR POWER-OFF DUE TO THE ADDITION OF THE
POWER LINE FILTER. IN ORDER TO AVOID THIS, THE SENSE CURRENT OF PROTECTIVE DEVICE
SHOULD BE SET HIGHER THAN VALUE OF LEAKAGE CURRENT SEEN DURING POWER UP OR
POWER DOWN.
RECOMMENDED FILTER INSTALLATION INSTRUCTIONS
To conform to the EMC directive, it is necessary that these instructions be followed as closely as possible.
Follow the usual safety procedures when working with electrical equipment. A qualified electrical technician
must make all electrical connections to the filter, drive and motor.
1) Check the filter rating label to ensure that the current, voltage rating and part number are correct.
2) For best results, the filter should be fitted as closely as possible to the incoming mains supply of the wiring
enclosure, usually directly after the enclosure’s circuit breaker or supply switch.
3) 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 to ensure the best
possible grounding of the filter.
4) Mount the filter securely.
5) Connect the mains supply to the filter terminals marked LINE; connect any earth cables to the earth stud
provided. Connect the filter terminals marked LOAD to the mains input of the drive using short lengths of
appropriate gauge cable.
6) Connect the motor and fit the ferrite cores (output chokes) as close to the drive as possible. Armoured or shielded
cable should be used with the 3 phase conductors only threaded twice through the center of the ferrite core. The
earth conductor should be securely grounded at both the drive and motor ends. The screen should be connected to
the enclosure body via a ground cable gland.
7) Connect any control cables as instructed in the drive instruction manual.
NOTE: IT IS IMPORTANT THAT ALL LEAD LENGHTS ARE KEPT AS SHORT AS POSSIBLE AND THAT
INCOMING POWER AND OUTGOING MOTOR CABLES ARE KEPT WELL SEPARATED.
