Assembling the System 
 WARNING 
The S500-FBP modules are not designed for removal or insertion under power. 
Because of unforeseeable consequences, it is not allowed to plug or unplug 
modules with the power being ON. 
 
If you connect or disconnect the FBP plug while power is applied to this module 
or the wiring while the process power supply is on, an electrical arc can occur. 
This could cause an explosion in hazardous location installations. 
 
Be sure that power is removed or area is non-hazardous before proceeding. 
 
Using S500 I/O Modules 
The S500 I/O modules could be used either directly connected to an AC500 CPU (central expansion) or 
together with an FBP Interface Module DC505-FBP + an FBP (PROFIBUS DP, DeviceNet, etc.) as 
decentralized expansion.
