WARNING
ELECTRICAL SHOCK HAZARD
VLT
®
FC series drives contain dangerous voltages when
connected to mains voltage. Improper installation, and
installing or servicing with power connected, can cause
death, serious injury, or equipment failure.
To avoid death, serious injury, or equipment failure:
•
Only use qualified electricians for the installation.
•
Disconnect the drive from all power sources before
installation or service.
•
Treat the drive as live whenever the mains voltage
is connected.
•
Follow the guidelines in these instructions and local
electrical safety codes.
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 off. Failure to wait the specified 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 20 minutes.
•
Before performing any service or repair work, use
an appropriate voltage measuring device to make
sure that the capacitors are fully discharged.
