EMC INSTALLATION GUIDE
CMC inverters are tested to meet Electromagnetic Compatibility (EMC) Directive 89/336/EEC and Low Voltage (LV)
Directive 73/23/EEC using a technical construction file. However, Conformity of the inverter with CE EMC requirements
does not guarantee an entire machine installation complies with CE EMC requirements. Many factors can influence total
machine installation compliance.
Essential Requirements for CE Compliance
Following conditions must be satisfied for CMC inverters to meet the CE EMC requirements.
1. CE compatible CMC inverter
2. Installing inverter in an EMC enclosure
3. Grounding enclosure and shielded parts of wire
4. RFI filter on inverter input side
5. Using shielded cable
1. Ferrite core on inverter output side
RFI FILTERS
THE L.G. RANGE OF POWER LINE FILTERS FF (Footprint) – FE (Standard) SERIES, HAVE BEEN SPECIFICALLY DESIGNED WITH HIGH
FREQUENCY CMC INVERTERS, THE USE L.G. FILTERS, WITH THE INSTALLATION ADVICE OVERLEAF HELP TO ENSURE TROUBLE FREE
USE ALONG SIDE SENSITIVE DEVICES AND COMPLIANCE TO CONDUCTED EMISSION AND IMMUNITY STANDARDS TO EN50081
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 LAKAGE CURRENT AT
WORST CASE IN THE BELOW TABLE.
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 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.
