15 Setup

15.1 Important notes

Only specialist personnel with extensive knowledge in the areas of electrical engineering /
drive technology are allowed to commission the drive unit of drive and motor.
Deadly voltages can occur, up to 900V. Risk of electric shock! Check that
all live connection points are safe against accidental contact.
Never undo the electrical connections to the motor when it is live. Risk of
electric shock! The residual charge in the capacitors of the drive can
produce dangerous voltages up to 10 minutes after the mains supply has
been switched off. Even when the motor is not rotating, control and power
leads may be live. Measure the DC-link voltage and wait until it has fallen
below 60V.
The surface temperature of the motor can exceed 100°C in operation.
Danger of light burns! Check (measure) the temperature of the motor.
Wait until the motor has cooled down below 40°C before touching it.
The drive performing unplanned movements during commissioning can-
not be ruled out.
Make sure that, even if the drive starts to move unintentionally, no danger
can result for personnel or machinery. The measures you must take in
this regard for your task are based on the risk assessment of the appli-
cation.
