1.2 Safety Instructions
WARNING
DISCHARGE TIME
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 the specied time 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 for the capacitors to discharge fully. The
minimum waiting time is specied in Ta bl e 1 .2 and
Tabl e 1. 3, and is also visible on the nameplate on
top of the drive.
•
Before performing any service or repair work, use
an appropriate voltage measuring device to make
sure that the capacitors are fully discharged.
