Chapter 4 Connecting the Kinetix 300 Drive System
Single-phase Power Wired to Single-phase Drives
These examples illustrate grounded single-phase power wired to single-phase
Kinetix 300 drives when phase-to-phase voltage is within drive specifications.
Figure 35 - Single-phase Grounded Power Configurations
(1) This configuration applies to voltage-doubler operation for 2097-V31PRx 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 drives with 120V input power and achieve twice
the output voltage at half the output current, while maintaining the same output
power. To use the voltage-doubler circuit, connect the 120V single-phase input
power to the IPD-L1 and IPD-N terminals.

input wiring diagrams, see Power Wiring Examples on page 173

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