* 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 is increased from the nominal level, 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.
Explosion-safe (EX) motors
Consult the motor manufacturer regarding the construction of the motor insulation and additional
