Connecting the power circuit
:DUQLQJ
The drive converters are operated at high voltages.
Only qualified personnel may carry-out work on the equipment.
All connecting-up work must be carried-out with the equipment in a no-voltage
condition.
The drive converter will be destroyed if the input- and output terminals are
interchanged!
The drive converter will be destroyed by interchanging or short-circuiting the DC
link terminals!
The user is responsible in ensuring that the drive converter, and other equipment is
installed and connected-up in accordance with the recognized regulations in the
country of installation as well as other regionally valid regulations. It is especially
important that the cables are correctly dimensioned, the equipment suitably
protected, grounded, shutdown, isolated and overcurrent protection.
Extreme care must be taken when working on the equipment in an open condition,
as external supply voltages may be present. The power terminals and control
terminals could be live (under voltage), even when the motor is stationary.
Perfect and safe operation of this equipment assumes that it has been
professionally transported, stored, installed and mounted as well as careful
operator control and maintenance.
Death, severe bodily injury or significant material damage could occur, if this
warning information is not observed.

) must be
routed between the motor and drive converter (connected to the grounding plate).
