Technical change to HDC RockStar ModuPlug SnapIn Module 
Dear Madam or Sir, 
the below listed articles will be supplied in a modified revision. Please pass this product information on to your 
employees and, if needed, to your customers. All modifications are performed for reasons of product 
improvements. 
1.  Initial situation 
The new, innovative and field attachable ModuPlug modules are equipped with the new SNAP IN 
connection technology. 
2.  Technical change 
From now on these modules will be delivered with the proven PUSH IN connection technology. 
3.  Reason for change 
Due to a change in internal processes, we had to create new article numbers for the new field attachable 
modules with SNAP IN connection. Therefore we can offer these modules additionally with PUSH IN 
connection under the previously known article number.
