Caution
The synchronous motors are not designed to be directly connected to the line supply and
may only be operated with the associated SIMODRIVE 611 or SIMOVERT
MASTERDRIVES MC drive converters.
Carefully observe the rating plate data and adequately dimension the connecting cables (the
appropriate tables are provided in the Instructions) and ensure that the cables are
adequately strain relieved.
For safety-relevant circuits, each individual application must be carefully checked as to
whether the internal control devices in the drive converter are adequate to provide the
appropriate electrical isolation from the line supply.
All work should be undertaken only with the system in a no-voltage condition!
