Opening the door
The following table shows you how the cubicle door can be opened using
the rotary switch extension for the door:
Table 2-10: Opening a cubicle door using the rotary switch extension
Opening the door with
great force
Note:
If the circuit breaker is in the ON position and the door is opened with a
force >150 N to 200 N, the cap of the extension shaft is separated from the
rotary switch of the circuit breaker to prevent the circuit breaker being
destroyed.
The circuit breaker remains in the ON position.

Drawing Procedure
To open the cubicle door, set the
circuit breaker to O (OFF). This
releases the extension shaft from
the rotary switch and allows the
door to be opened.
If you want to open the cubicle
door during operation, you can
override the procedure by press-
ing the button at the side of the
rotary knob (step
1
).
To close it during operation, press
the button again so that the exten-
sion shaft snaps into place again.
