or serious injury.

-Stop the motor.

-Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and

DC-link connections to other drives.

-Wait for the capacitors to discharge fully. The minimum waiting time is specified in table Discharge time and is also visible

-Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors

are fully discharged.
