* manufactured before 1.1.1998
** For motors manufactured before 1.1.1998, check for additional instructions with the motor manufacturer.
*** If the intermediate DC circuit voltage of the drive will be increased from the nominal level by resistor braking or
by the IGBT supply unit control program (parameter selectable function), check with the motor manufacturer if
additional output filters are needed in the applied drive operation range.
Note 1: The abbreviations used in the table are defined below.
Note 2: Explosion-safe (EX) motors
The motor manufacturer should be consulted regarding the construction of the motor insulation and
additional requirements for explosion-safe (EX) motors.
Note 3: High-output motors and IP 23 motors
For motors with higher rated output than what is stated for the particular frame size in EN 50347 (2001)
and for IP 23 motors, the requirements of ABB random-wound motor series M3AA, M3AP, M3BP are
