WARNING

DISCHARGE TIME

The frequency converter contains DC-link capacitors, which
can remain charged even when the unit is off. High voltage
can be present even when the warning indicator lights are
off. Failure to wait 20 minutes after power has been
removed before performing service or repair work, could
result in death or serious injury.
