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 o. 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.
