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.

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 for the specified time listed in
Table 1.2 after power has been removed before performing
service or repair work can result in death or serious injury.
