Maintenance work on electrical components may only be carried out by au-
thorized personnel (electricians). Make sure that the electrical equipment of
the machine is de-energized for the period of maintenance.
Wait at least 15 minutes before removing the protective hood of the machine.
The DC bus capacitors must first discharge themselves independently during
this period.

hood. Only then will the capacitors be discharged under
the protective hood.

tive hood on it.
Alternatively, you can also use a tool trolley or other suit-
able facility.
3. Remove the 2 side Phillips screws from the protective
hood.

hold it, so that you can reach under the protective hood
from the front or the side.

pulling the release button on the plug.
The other plug can remain connected.
