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 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.
