ABB ACH580-01 - Additional Requirements for Non-ABB High-Output and IP23 Motors

This table shows the requirements for protecting the motor insulation and bearings in
drive systems for ABB random-wound motor series (for example, M3AA, M3AP and
M3BP).

Additional requirements for non-ABB high-output and IP23 motors
The rated output power of high-output motors is higher than what is stated for the
particular frame size in EN 50347 (2001).
If you plan to use a non-ABB high-output motor or an IP23 motor, consider these
additional requirements for protecting the motor insulation and bearings in drive systems:
• If motor power is below 350 kW: Equip the drive and/or motor with the filters and/or
bearings according to the table below.
• If motor power is above 350 kW: Consult the motor manufacturer.
