An RFI (radiofrequency interference) filter reduces the electromagneticnoise in the mains supply. Without an RFI filter, there is arisk that a frequency converter disrupts other electricalcomponents that are connected to the mains and mightthus cause operating disruption. By fitting an RFI 1B filtermodule between the mains supply and the VLT 2800, theVLT 2800 complies with the EMC norm EN 55011-1B.To comply with EN 55011-1B, the RFI 1B filter module mustbe fitted together with a VLT 2800 with integral 1A RFIfilter.Illustration 1.3 RFI 1B Filter ExampleMaximum cable length (screened/armoured)200-240 V100 m (At 1A: 100m)Maximum cable length (screened/armoured)380-480 V25 m (At 1A: 50m)Enclosure IP20Maximum rated current 16 AMaximum Voltage 480 V ACMaximum voltage to ground 300 V ACMinimum distance between VLT and RFI 1BfilterSide-by-sideMinimum distance above and below RFI 1Bfilter100 mmMounting Vertical mountingonlyDimensions HxWxD (mm) 200x60x87Weight 0.9 kgTable 1.5 Technical Data for VLT 2803–2875 RFI 1B FilterFor ordering number for RFI 1B filter module, seechapter 1.10 Accessories for VLT 2800.Introduction to VLT 2800 Design Guide12 Danfoss A/S © Rev.
