You require the following tools: 

●  slotted screwdriver with a 2.8 mm wide blade 

●  slotted screwdriver with a 5.5 mm wide blade 

 

 

Note 
Make sure that in addition to the extender width of 155 mm, there is a clearance of 
20 mm to the right of the basic device on the S7-300 rail to be able to align the 
guide bolts of the extender with the holes in the basic device during installation. 

 

 

Note 
Protective caps and CV490 2x100 covers must be fitted to all slots without media 
modules. 

When installing a media module extender on an S7-300 rail, the basic device re-
mains in position. Follow the steps below: 

1.  Remove the cover from slot 11 of the basic device. 

2.  Remove the right-hand side panel of the basic device. To do this, use a slotted 

screwdriver with a 2.8 mm wide blade to loosen the two captive slug screws on 
slot 11 in the upper and lower recesses as far as they will go. 

3.  Remove the side panel of the basic device from the basic device to the right. 

 

Note 
Keep the panel in a safe place in case the extender needs to be removed 
again later. 

4.  Remove the four covers from the extender. 

5.  Place the extender module on the edge of the S7-300 rail with the upper 

groove angled slightly towards the back and tilt the extender towards the back. 
Make sure that there is adequate clearance between the guide bolts of the ex-
tender module and the basic device. In this position, the extender module 
should not be able to slip off, however it can be moved horizontally in both di-
rections.
