Chapter 4 Connect the Kinetix 3 Drive
Three-phase Power Wired to Single-phase Drives
This example illustrates grounded three-phase power wired to single-phase
Kinetix 3 drives when phase-to-phase voltage is within drive specifications. The
optional grounded neutral is omitted on ungrounded systems.
Figure 27 - Single-phase Amplifiers on Three-phase Power (WYE)
(1) AC line filter is optional, but is required for CE compliance.
Feeder short circuit protection is not illustrated.
If a three-phase line filter is used to feed multiple single-phase drives (not
recommended), it is important that the filter include a neutral connection as
shown above. This applies if three-phase is brought directly into the filter and no
isolating transformer is present.
