Mounting instructions 

The modular automation stations are particularly suitable for control panel front 
mounting as well as flush-panel and wall mounting. 
For control panel front mounting the device socket is held in place by clamps at all four 
corners (no tools required for mounting). The upper housing is fixed to the device 
socket with two screws. 
For flush panel mounting the plug-in terminal blocks can be repositioned whilst at the 
same time reversing the support bars to enable front access. The support bars absorb 
the screw force and also provide the means of fixing the device to the wall. 

Instead of the front cover a PXM... operator unit can be fitted on the modular auto-
mation station.  

For 

PXM20-E

 mounting (ethernet cable) see the mounting instructions delivered with 

the operator unit! 
 

•

 Insert 

the 

PXA30… extension module

 fully 

into its socket (

to a depth of 

1.5 mm), 

using slight force. 

Then 

check that the plug is safely snapped on

 to ensure safe 

and smooth functioning. 

•

 

Do not touch

 the connector pins (electrostatic discharge) 

Note 

STOP

 

Note!
