Safety
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.
•
Stop the motor.
•
Disconnect the AC mains, permanent magnet type
motors, and remote DC-link supplies, including
battery back-ups, UPS, and DC-link connections to
other frequency converters.
•
Wait 20 minutes for the capacitors to discharge fully,
before performing any service or repair work.
•
Measure the voltage level to verify full discharge.
Installation
NOTICE
If both a bus bar kit and a back-channel cooling kit are
