Operation on an impedance grounded system
When using the ATV31 drive controller on a system with an isolated or impedance grounded neutral,
use a permanent insulation monitor compatible with non-linear loads.
ATV31••••M2 and N4 drives feature built-in RFI filters with grounded capacitors. When using the drive
on an impedance grounded system, we recommend isolating the RFI filters from ground to prevent
reduction of their operating life. For more information, refer to “Operation on an Impedance Grounded
System” in the Altivar

31 Installation Manual, VVDED303041US.
(1) Refer to the drive controller nameplate or to the fuse tables for recommended fuses.
Fast acting or time delay Class J fuses can be used.
(2) Fault relay contacts for remote indication of drive controller status.
(3) Internal +24 V. If an external source is used (30 V maximum), connect the 0 V terminal of
the source to the 0 V (COM) terminal, and do not use the +24 V terminal on the drive
controller for any purpose.
(4) Line reactor, if used. All 575 V installations must include a line reactor.
(5) Installation of a load filter is recommended for all 575 V applications.
