2.1 Safety Instructions

DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be
present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work could result in death 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 4 minutes and is also visible on the nameplate on the
top of the drive.
-
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors
are fully discharged.
