•
Disconnect any dangerous external voltages from the control circuits.
•
After you disconnect power from the drive, always wait 5 minutes to let the
intermediate circuit capacitors discharge before you continue.
3.
Protect any other energized parts in the work location against contact.
4.
Take special precautions when close to bare conductors.
5.
Measure that the installation is de-energized.
•
Use a multimeter with an impedance greater than 1 Mohm.
•
Make sure that the voltage between the drive input power terminals (L1, L2, L3)
and the grounding (PE) busbar is close to 0 V.
•
Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W)
and the grounding (PE) busbar is close to 0 V.
6.
Ask the person in control of the electrical installation work for a permit to work.
