Requirements table

The following table shows how to select the motor insulation system and when an
optional drive du/dt 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.
