Opening the housing
The device should only be opened when it is mounted on a wall or installed in a control panel.
To open the housing, initially, the four captive countersunk screws must be released.
The upper section is additionally locked to the bottom section by means of snap hooks. The housing can
be opened by pulling the upper section forward thus releasing the snap hooks.
With the aid of the two guide rails, the upper section can be moved to the approx. 100 mm higher "park
position". The fuse and all connection terminals are freely accessible in the park position.
