Hello Sid, When you are selecting 400-F CPU it's only allowed to mount it on either UR-2 ALU RACK or CR ALU Rack only. Reason behind this is that these racks are specially manufactured to get adjusted with any sort of S7 400 series PLC's. UR-2 normal rack is only for mounting normal standalone S7 400 series CPU's along with other peripheral devices like IO modules, CP cards, etc. F CPU's are special type of CPU's for special applications where process dependancy is at topmost priority & no sort of external faults can cause the process to withhold. That's why F-series CPU's are used in those sort of applications. Also you can search the topic in web giving the MLFB of the CPU & refer the datasheet of that CPU also.
