Hello Guys

Actually i was reading this manual and having hard times.

I am posting 3 pictures from the same manual. the 3 of them states that this is the configuration for S7-300 Configuration with PS307 as power supply for the CPU and the Load circuit. For me i noticed that 2 of those 3 pictures are not the case of PS as power supply for the load ciruit. Is there something I am missing? 

------------------------------------------------------------------------------------------
Split from S7-300 with grounded & ungrounded reference potential.

why you think so?
All 3 pictures display the wiring of load circuit.

maybe you not read the remark?
The Powerconnectors are symbolic displayed and not the physical arrangement.

The paragraph above the circuit in each pic determines that the PS 307 supplies the power to the CPU and the Load Circuit of the Modules. But the Load circuit in the Pic1 and Pic2 are derived from the Transformers, while in Pic3, the load circuit is connected to the PS 307. 

so i was wondering if the paragraph meant something else.
