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 LED indicator lights
are off. Failure to wait 40 minutes after power has been
removed before performing service or repair work can result
in death or serious injury.
•
Stop the motor.
•
Disconnect AC mains and remote DC-link power
supplies, including battery back-ups, UPS, and DC-
link connections to other drives.

Disconnect or lock PM motor.

Wait 40 minutes for capacitors to discharge fully.

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