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
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 5 displays an electrical schematic for various RFI configurations. Table 2 shows associated RFI filter part numbers.
CAUTION
ELECTRIC SHOCK HAZARD! Service and
maintenance to be performed only by an authorized technician. Disconnect power before opening any access panels.
