Use on an impedance grounded (IT) system
Principle
When using the ATV212 drive on a system with an isolated or impedance grounded neutral, use a permanent
insulation monitor compatible with non-linear loads, such as a XM200 type or equivalent.
ATV212 480 V rated drives feature built-in radio frequency interference (RFI) filters with grounded capacitors.
When using the drive on an impedance grounded system, we recommend that you isolate the RFI filters from
ground to help prevent reduction of their operating life.
Jumper Location
ATV212H075N4 to U55N4, ATV212H D22N4 to D30N4:
Pull out the jumper to the left of the ground terminal as illustrated below to isolate the RFI filters.
ATV212HU75N4 to D22N4S:
Connect the cable to the top left of the power terminals as illustrated below to isolate the filters.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Read and understand the instructions in "before you begin" chapter, before performing the procedure in this
