Electrical Interference
EMI
Careful attention must be given to the arrangement of
power and ground connections to the drive to avoid
interference with nearby sensitive equipment. Be sure
to replace all ground connections to their appropriate
locations.
RFI
Drives can be installed with an RFI filter, which
controls high-frequency conducted emissions into the
main supply lines.
Where it is essential that very low emission levels
must be achieved or if conformity with standards is
required, the optional RFI filter may be present.
Figure 47 displays an electrical schematic for various
RFI configurations. Table 47 shows associated RFI
filter part numbers.
