52 Guidelines for planning the electrical installation
Additional requirements for ABB motors of types other than M2_, M3_, M4_, HX_
and AM_
Use the selection criteria given for non-ABB motors.
Additional requirements for 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). This table shows the requirements 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). The table below shows the requirements for random-
wound and form-wound non-ABB motors with nominal power smaller than 350 kW. For
bigger motors, consult the motor manufacturer.
