Single-phase Power Wired to Single-phase Drives
These examples illustrate grounded single-phase power wired to single-phase
Kinetix 350 drives when phase-to-phase voltage is within drive specifications.
Figure 29 - Single-phase Grounded Power Configurations
(1) This configuration applies to voltage-doubler operation for 2097-V31PRx-LM drives.
Reducing transformer output reduces motor speed. Feeder and branch short
circuit protection is not illustrated.
Voltage Doubler Operation
You can wire the 2097-V31PRx-LM drives with 120V input voltage and achieve
twice the output voltage. To use the voltage-doubler circuit, connect the 120V
single-phase input power to the IPD-L1 and IPD-N terminals.

IMPORTANT
The 2097-V32PRx-LM models have integrated AC line filters and do not require
the AC line filter shown in this diagram.
