ACQ800-37 Hardware Manual 55
Planning the electrical installation
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.
* 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.
