1.  Carefully align the module with the guides (located at the top and 
bottom of the case). Gently slide the module into the case until it 
seats fully with the appropriate connector on the backplane.  
2.  Press each of the two ejectors securely into place once the module 
is fully inserted.  
 
Inserting and seating a module along the guides does not require 
excessive force. Take care not to twist or otherwise distort the module 
during the installation. 
 
3.  Secure the module with the retention screws (two per board).   
2.6  Installing EMC Protection 
Your site may require you to install electromagnetic compatibility 
(EMC) shielding on the S600+ to minimize electromagnetic 
interference. The S600+ EMC protection kit (which came with your 
S600+) typically has the following components:  
  1 security backplate (place over the installed modules)  
  1 25-way EMISTOP Inline T Filter Adaptor (attach to the 25-pin 
socket A on the I/O module) 
  1 37-way EMISTOP Inline T Filter Adaptor (attach to the 37-pin 
socket B on the I/O module) 
  3 large (for 13mm cable) ferrite clamps  
  3 medium (for 10mm cables) ferrite clamps  
  1 small (for 6.5mm cables) ferrite clamp
