Installing the device in a housing or a control cabinet
The SITOP select and SITOP PSE200U selectivity modules are built-in units. They must be
installed in a housing or control cabinet where only qualified personnel have access.
The device can be mounted in a control cabinet on standard mounting rails according to
EN 60715 35×7,5/15.
To mount the device, position it with the mounting rail guide at the upper edge of the
standard mounting rail and press down to lock it into place. If it is too difficult to snap them
into place, press slider
① at the same time, as described under "Removal".
To remove, pull up the slider ① using a screwdriver ② (see Chapter Figure 3-1
Mounting/removal (example): 6EP1961-2BA11) (Page 31)) and disengage the device at the
bottom edge of the standard mounting rail. Then you can remove the device from the upper
edge of the standard mounting rail.
