IMPORTANT Even though corner-grounded power configurations have a ground
connection, treat them as ungrounded when installing Kinetix 5500 drive
systems.
IMPORTANT If you determine that you have ungrounded or high-impedance grounded
power distribution in your facility, you need to remove the grounding screws.
Refer to Removing the Grounding Screws in Ungrounded Power Configurations
on page 71 for more information.
