2.1 Safety Information

NOTICE

QUALIFIED PERSONNEL

Only qualified, Danfoss authorized personnel are allowed to install the parts described in these installation instructions.

Disassembly and reassembly of the frequency converter must be done in accordance with the service guide.

Use the standard fastener torque values from the service guide, unless the torque value is specified in these instructions.

WARNING

ELECTRICAL SHOCK HAZARD

Danfoss frequency converters contain dangerous voltages when connected to mains voltage. Improper installation, and instal-

ling or servicing with power connected, can cause death, serious injury, or equipment failure.

Only use qualified electricians for the installation.

Disconnect the frequency converter from all power sources before installation or service.

Treat the frequency converter as live whenever the mains voltage is connected.

Follow the guidelines in these instructions and local electrical safety codes.

WARNING

DISCHARGE TIME

The frequency converter contains DC-link capacitors, which can remain charged even when the frequency converter is not pow-

ered. 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

frequency converters.

Disconnect or lock the motor.

Disconnect any brake option.

Disconnect any regen/load share option.

Wait for the capacitors to discharge fully. The minimum waiting time is listed on the frequency converter label and also in the

following discharge time table.

Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors

are fully discharged.
