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 qualied 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 o. Failure to wait 40 minutes 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.

Before performing any service or repair work, use

an appropriate voltage measuring device to make
