2 Safety
2.1 Safety Precautions
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 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.

General Technical Data
3 General Technical Data
3.1 Galvanic Isolation
Digital/analog inputs are galvanically isolated from other inputs/outputs on the VLT® General Purpose I/O MCB 101 and in the control
card of the drive.
Digital/analog outputs in the VLT® General Purpose I/O MCB 101 are galvanically isolated from other inputs/outputs on the VLT®
General Purpose I/O MCB 101, but not from those on the control card of the drive.
