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 and voids
the warranty.
