Requirements Table
The following table shows how to select the motor insulation system and when an
optional ABB du/dt filter, insulated N-end (non-driven end) motor bearings and ABB
common mode filters are required. The motor manufacturer should be consulted
regarding the construction of the motor insulation and additional requirements for
explosion-safe (EX) motors. Failure of the motor to fulfil the following requirements
or improper installation may shorten motor life or damage the motor bearings.
