1.7.10 RFI 1B Filter
All frequency converters cause electromagnetic noise in
the mains supply when they are operating. An RFI (radio
frequency interference) filter reduces the electromagnetic
noise in the mains supply. Without an RFI filter, there is a
risk that a frequency converter disrupts other electrical
components that are connected to the mains and might
thus cause operating disruption. By fitting an RFI 1B filter
module between the mains supply and the VLT 2800, the
VLT 2800 complies with the EMC norm EN 55011-1B.
To comply with EN 55011-1B, the RFI 1B filter module must
be fitted together with a VLT 2800 with integral 1A RFI
filter.
