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.
