Requirements tables
These tables show how to select the motor insulation system and when a drive
d u /d t and common mode filters and insulated N-end (non-drive end) motor
bearings are required. Ignoring the requirements or improper installation may
shorten motor life or damage the motor bearings and voids the warranty.
