13 Electromagnetic Compatibility (EMC) 
13-1   General 
In accordance with the provisions described in the European Commission Guidelines Document on 
Council Directive 89/336/EEC,GE Fuji has chosen to classify the AF-300C11 range of Drives as "Com-
plex Components".  
Classification as a "Complex Components" allows a product to be treated as an "apparatus", and thus 
permits compliance with the essential requirements of the EMC Directive to be demonstrated to both 
an integrator of AF-300C11 Drives and to his customer or the installer and the user. 
AF-300C11 Drives are supplied `CE-marked', signifying compliance with EC Directive 89/336/EEC 
when fitted  with specified filter units installed and grounded in accordance with this sheet. 
This Specification requires the following performance criteria to be met. 
 
EMC product standard  EN61800-3/1996 
 
  Immunity : Second environment  ( Industrial environment ) 
  Emission : First environment ( Domestic environment ) 
 
 Finally, it is customer’s responsibility to check whether the equipment conforms to EMC 
 directive. 
 
 
 
13-2   RFI Filters  
It is strongly recommended that the appropriate AF-300C11 input filter is used, as shown in the fol-
lowings, to limit RF current flowing into the main supply circuit. Without an input filter a AF-300C11 
installation may not meet statutory requirement. AF-300 Drives contain high-power semi-conductor 
devices which are switched at high speeds to synthesize a near-sinusoidal current wave form across 
the frequency range of output. Rapidly-changing voltages and currents will generate some degree of 
electromagnetic emission. Emissions will be predominantly conducted through the motor and the 
mains supply cables, although some radiated emissions will be detected in close proximity to the 
drive system. It is essential that precautions are taken both at the design stage and at the time of in-
stallation to prevent radio frequency interference (RFI) from the drive system affecting sensitive 
equipment in close proximity. 
The RFI filters range are designed especially for the AF-300C11 Drive and help to ensure EMC com-
pliance of machinery an installations using the Drives. The Drives single phase series may be 
mounted on top of the filter using the integral fixing positions, the intention being that valuable space 
inside wiring cabinets may be saved. (Refer to Table 13-2-2)
