
Requirements table
The following table shows how to select the motor insulation system and when optional
ABB d
u /d t filters, insulated N-end (non-drive end) motor bearings and ABB common mode
filters are required. Failure of the motor to fulfill the following requirements or improper
installation may shorten motor life or damage the motor bearings and voids the motor
warranty.
