3.5.8.3 - Radiated emissions
When the drive, associated with one of the
RFI filters listed in section 3.5.7, is installed
in a steel cabinet and the wiring
recommendations have been adhered to, it
meets the limits for radiated emissions
defined in the generic emission standard for
residential environments,
EN 50081-1 (0.5M to 1.5M ratings only) and
the generic emission standard - industrial
environment part EN 50081-2 (1.5M/TL to
50T ratings).
Tests have been carried out with an
enclosure representative of the most
common installations. It may be, on a
device with different characteristics,
that the levels of radiated emissions are
not identical to those identified during
tests.
The tables below summarise the radiated
emission results and indicate the six least
favourable measurements between 30 and
1000 MHz.
Note:
• Level authorised by standard EN 50081-1
at 10 m is 30 dBµV/m.
• Level authorised by standard EN 50081-2
is 40 dBµV/m.
