®
series drives contain dangerous voltages when

installing or servicing with power connected, can cause
death, serious injury, or equipment failure.
To avoid death, serious injury, or equipment failure:

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.

Disconnect AC mains and remote DC-link power
supplies, including battery back-ups, UPS, and DC-
link connections to other drives.
