Removing the Grounding
Screws in Ungrounded Power
Configurations

Removing the grounding screws is necessary only when using ungrounded or
corner-ground power configurations. Removing the screws involves gaining
access, opening the sliding door, and removing the screws.

Removing the grounding screws in multi-axis configurations is best done when
the drive is removed from the panel and placed on its side on a solid surface
equipped as a grounded static-safe workstation.

ATTENTION: Ungrounded systems do not reference each phase potential to a
power distribution ground. This can result in an unknown potential to earth
ground.

IMPORTANT

If you have grounded power distribution, you do not need to remove the
grounding screws. Go to

Grounding the Drive System

on

page 73

.

IMPORTANT

Removing the grounding screws can affect EMC performance.

ATTENTION: By removing the grounding screws for ungrounded power
configurations, you no longer maintain line-to-neutral voltage protection.
