Figure 15 - Three-phase (240V) Power Configuration (Delta Secondary)
(1)
Leakage current from the line filter, in this configuration, typically is higher than a balanced (center ground) configuration.
Single-phase Power Wired to Single-phase Drives
These examples illustrate grounded single-phase power that is wired to single-
phase Kinetix 350 drives when phase-to-phase voltage is within drive
specifications.
Figure 16 - Single-phase Grounded Power Configurations
ATTENTION:
For the 480V Kinetix 350 drives to meet proper voltage creepage and
clearance requirements, each phase voltage to ground must be less than or equal to
300V AC rms. This requirement means that the power system must use a center
grounded wye secondary configuration for 400/480V AC mains. Refer to Kinetix 350
EtherNet/IP Indexing Servo Drives User Manual, publication
for leakage
currents.
