2. Drive setup
2. 8. Power wiring
The layout and type of power terminals have changed:
Ring terminals must be used rather than ferrules for the ground terminals, although for the power terminals the ferrules used previously can
be retained if they are in good condition (a flattened ferrule will not make a good connection).

IT system: Isolated or impedance grounded neutral.
Use a permanent insulation monitor compatible with non-linear loads: a Merlin Gerin type
XM200 or equivalent.
Altivar 71 drives feature built-in RFI filters. These filters can be isolated from ground for
operation on an IT system as follows:
