START-UP

Internal components and circuit boards of the drive are live
when the drive is connected to incoming power. Coming into
contact with this voltage is extremely dangerous and will result
in severe personal injury or death.
The motor terminals U, V, W and the DC-link terminals are
live when the drive is connected to incoming power, even if
the motor is not running.
Do not make any connections when the drive is connected to
the incoming power.
After having disconnected the drive, wait until all LEDs have
ceased emitting light. Wait 5 more minutes, and check for haz-
ardous voltage with volt meter, before doing any work on drive
connections. Do not even open the cover before this time has
expired.
Before connecting the drive to the incoming power, make sure
that the switchgear enclosure door is closed.
WARNING
The control I/O-terminals are isolated from the mains poten-
tial. However, the relay outputs and other I/O terminals may
have a dangerous control voltage present even when the drive
is disconnected from incoming power. Coming into contact
with this voltage could result in severe personal injury.
When working with the Connected Components Workbench
(CCW), never use the Rotate function as the motor will imme-
diately start and severe compressor damage could result.
