7.4 Replacing the SINAMICS G120C converter
WARNING
Danger to life as a result of unexpected machine movement when the hardware or firmware
is changed
The drive can malfunction after replacing drive components or updating the firmware. This
can place people at risk or cause material damage.
● Before switching on the power supply voltage again, ensure that nobody is in the
dangerous area around the machine.
● Close the protective devices available before you switch on the power supply voltage.
● Check the stability of the closed-loop control, for example, by briefly moving the drive in
both directions of rotation.
● Perform a reduced acceptance test.
