9.2.2
Grounding using a make-proof grounding switch
The drive is equipped with a make-proof grounding switch (in compliance with the requirements
of IEC61800-5-1, Section 4.2.13).
You can close the make-proof grounding switch when the doors are closed and only at a
voltage below 60 V. If the auxiliary voltage fails completely, the make-proof grounding switch
cannot be closed. It is not permissible that you open the doors before the make-proof grounding
switch is closed.
WARNING
Danger to life as a result of a DC link short-circuit
A DC link short-circuit can occur if you ground the drive under voltage. This can result in death,
serious injury or material damage.
● Remove the socket wrench before switching on the power. This activates the interlocking.
