Wiring<br />
When using the ATV<strong>31</strong> drive controller on a system with an isolated or impedance grounded neutral,<br />
use a permanent insulation monitor compatible with non-linear loads.<br />
LI4<br />
(1) Refer to the drive controller nameplate or to the fuse tables for recommended fuses.<br />
Fast acting or time delay Class J fuses can be used.<br />
(2) Fault relay contacts for remote indication of drive controller status.<br />
(3) Internal +24 V. If an external source is used (30 V maximum), connect the 0 V terminal of<br />
the source to the 0 V (COM) terminal, and do not use the +24 V terminal on the drive<br />
controller for any purpose.<br />
(4) Line reactor, if used. All 575 V installations must include a line reactor.<br />
(5) Installation of a load filter is recommended for all 575 V applications.<br />
ATV<strong>31</strong> M2 and N4 drives feature built-in RFI filters with grounded capacitors. When using the drive<br />
on an impedance grounded system, we recommend isolating the RFI filters from ground to prevent<br />
reduction of their operating life. For more information, refer to “Operation on an Impedance Grounded<br />
System” in the <strong>Altivar</strong> ® <strong>31</strong> Installation Manual, bulletin number VVDED303041US.<br />

NOTE: The line supply terminals are shown at the top, and the motor<br />
terminals are shown at the bottom. Use surge suppressors on all inductive<br />
circuits located near the drive controller or coupled to the same circuit.<br />
