16.3 EMC Filters
RECOMMENDED 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. All electrical
connections to the filter, inverter and motor must be made by a qualified electrical technician.
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 enclosures 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 earth connection 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 inverter
using short lengths of appropriate gauge cable.
6-) Connect the motor and fit the ferrite core ( output ferrite ring ) as close to the inverter as
possible. Armoured or screened 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 earthed at both
inverter and motor ends. The screen should be connected to the enclosure body via and earthed
cable gland.
7-) Connect any control cables as instructed in the inverter instructions manual.
IT IS IMPORTANT THAT ALL LEAD LENGTHS ARE KEPT AS SHORT AS POSSIBLE AND
THAT INCOMING MAINS AND OUTGOING MOTOR CABLES ARE KEPT WELL SEPARATED.
EMI / RFI POWER LINE FILTERS
THE ES RANGE OF POWER LINE FILTERS FFM (Footprint) AND FV SERIES, HAVE BEEN
SPECIFICALLY DESIGNED WITH HIGH FREQUENCY ES INVERTERS. THE USE OF ES FILTERS,
WITH THE INSTALLATION ADVICE OVERLEAF HELP ENSURE TROUBLE FREE USE ALONG
SIDE SENSITIVE DEVICES AND COMPLIANCE TO CONDUCTED EMISSION AND IMMUNITY
STANDARDS EN61800-3.
CAUTION
IN CASE OF LEAKAGE CURRENT, A PROTECTIVE DEVICE IS USED ON POWER SUPPLY, THAT
COULD BE DAMAGED WHEN POWERING ON/OFF THE DEVICE. TO AVOID THIS, THE SENSE
CURRENT OF THE PROTECTIVE DEVICE SHOULD BE LARGER THAN THE VALUE OF THE
LEAKAGE CURRENT. SEE TABLE BELOW.
