ATTENTION: This drive contains electrostatic discharge (ESD) sensitive parts
and assemblies. You are required to follow static-control precautions when you
install, test, service, or repair this assembly. If you do not follow ESD control
procedures, components can be damaged. If you are not familiar with static
control procedures, refer to Guarding Against Electrostatic Damage, publication
8000-4.5.2
, or any other applicable ESD awareness handbook.
Ground screws installed
for grounded power configuration
(screws installed is default setting).
Remove screws for ungrounded power.

Both screws installed (default setting)
• UL and EMC compliance
• Reduced electrical noise
• Most stable operation
• Reduced voltage stress on components
and motor bearings
• B-phase corner ground
• AC fed ungrounded
