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 enclousure,
usually directly after the enclousures 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
earthing 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 chokes ) 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 LENGHTS ARE KEPT AS SHORT AS POSSIBLE AND THAT INCOMING MAINS
AND OUTGOING MOTOR CABLES ARE KEPT WELL SEPARATED.

RFI FILTERS
THE LS RANGE OF POWER LINE FILTERS FF ( Footprint ) - FE ( Standard ) SERIES, HAVE BEEN SPECIFICALLY
DESIGNED WITH HIGH FREQUENCY LS INVERTERS. THE USE OF LS FILTERS, WITH THE INSTALLATION ADVICE
OVERLEAF HELP TO ENSURE TROUBLE FREE USE ALONG SIDE SENSITIVE DEVICES AND COMPLIANCE TO
CONDUCTED EMISSION AND IMMUNITY STANDARS TO EN 50081 -> EN61000-6-3:02 and EN61000-6-1:02
CAUTION
IN CASE OF A LEAKAGE CURRENT PROTECTIVE DEVICES IS USED ON POWER SUPPLY, IT MAY BE FAULT AT
POWER-ON OR OFF. IN AVOID THIS CASE, THE SENSE CURRENT OF PROTECTIVE DEVICE SHOULD BE LARGER
THAN VALUE OF LEAKAGE CURRENT AT WORST CASE IN THE BELOW TABLE.
