1.4 Safety Instructions

For important information about safety precautions for installation, refer to the product-specific operating guide.

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 indicator lights are off.

Failure to wait the specified time after power has been removed before performing service or repair work could result in death

or serious injury.

-Stop the motor.

-Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and

DC-link connections to other drives.

-Wait for the capacitors to discharge fully. The minimum waiting time is specified in the table Discharge time and is also

visible on the nameplate on top of the drive.

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

are fully discharged.
