1.2 Safety Information

Only qualied, Danfoss-authorized personnel are allowed to

install the parts described in these installation instructions.

Disassembly and reassembly of the drive must be done in

accordance with the corresponding service guide.

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 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 20 minutes.

•

Before performing any service or repair work, use

an appropriate voltage measuring device to make

sure that the capacitors are fully discharged.

NOTICE

ELECTROSTATIC DISCHARGE

Follow proper ESD precautions to prevent damage to

sensitive components.
