ATTENTION: RTP and cables are intended for permanent installation within their own enclosure. 
ATTENTION: The RTP labeled “DI, DO, AO RTP ASSY” with jumpers J2-J9 is the correct one for 16 
point AI. 
Mount RTP cable assembly to HC900 Controller (Figure 96). 
  Remove appropriate key tabs from terminal board to allow mating with the module. See page 85. 
  Connect terminal block end of desired cable assembly to 16 point Analog Input module at controller. 
Choose from: 
900RTC-3210  Remote Terminal Cable assembly, 1.0 meters long  
900RTC-3225  Remote Terminal Cable assembly, 2.5 meters long   
  Install 16 point Analog Input label into the module connector cover. 
  Connect both shield drain wires to the grounding bars at the base of the HC900 rack.  All field-wiring 
shields must be grounded as described in the shield grounding section (page 81).
